JCB make fine diesel engines and earth moving machinery



The JCB DIESELMAX will attempt the speed record for a diesel-powered automobile in August 2006 at the Bonneville Salt Flats, Utah. Powered by a pair of advanced 4-cylinder, 5-litre JCB444-LSR diesels, developed with the support of Ricardo, the JCB DIESELMAX is said to boast the world's highest specific power diesel engines used in any automobile application Ricardo applied its state-of-the-art powertrain computer aided engineering software to the task of assisting JCB in the development of the JCB444-LSR engines which deliver peak power of 750hp and torque of 1500Nm.

The engines are more than five times the power of the production version and at 150hp/litre, they exceed even motorsport applications as the world's highest specific power diesels. Ricardo Director of Diesel Engineering, Ian Penny, said: "We are pleased to have been asked to play the role of JCB's engine development partner on this high profile and exciting project....and we wish JCB every success in breaking the land speed record for a diesel powered vehicle."




Temperature: 29°C

Following eight runs the night before at Wendover airfield, the team completed a further six runs before 09.00 this morning. The aim was to test the software change made to the engine management system to reduce the fuelling of the front engine in first gear so increasing the load to the rear engine and pushing it on to boost.

It appeared to be successful with both engines going on to boost even though it was only possible to engage second gear for a few seconds.

Based on this result we took the car on to the Salt Flats but the JCB team faced a long queue because running was delayed until 10.30 due to high cross winds.

The car moved slowly along the line from 11.30 until 17.09 when the car’s 42nd run got underway; the JCB DIESELMAX was the penultimate car to run today. In the run the rear engine went on to boost in first gear as planned, but in second gear the front engine didn’t pick up. Despite three attempts to bring the boost up, including de-clutching the rear engine, the front engine didn’t go onto boost. It had already been motored beyond the speed at which it will load up.

In simple terms the technical changes had transferred the rear boost problem on to the front engine. Top speed was 186mph.

The car was immediately taken back to airfield and in the heat of the early evening the team set to work on a mechanical change to the engine system. They faced working all night to manufacture a balance bar to connect the two boost systems. Tomorrow morning the new parts will be fitted and some electronic control system changes installed.

The JCB has completed its fourth consecutive day of running on the salt.





Record Attempt News 17 August 2006 - 300 mph




4 August 2006 - Andy clocks up 190mph in JCB Max


A long yellow missile sped along the runway, straight as a die, almost silently, like a golden arrow. The car is the JCB Diesel Max Streamliner in action on its first public outing.

Andy Green, the fastest man on four wheels and the first driver to go supersonic, was behind the steering wheel – and as the speedo clocked 190mph he wore a quiet smile of satisfaction.

RAF Wittering on Monday was Grp Capt Green's home territory and JCB's target is to develop the fastest diesel engine in history. Andy, who normally flies 600mph Harriers, was the obvious choice to steer the yellow monster.

The isolated 1.6-mile runway at Wittering was also an obvious choice because its surface was said to be highly compatible with that of the Bonneville Salt Flats in Utah where Andy, 44, broke the land speed record in 1997 with a drive of 763mph.

Now he will lead an attempt on the diesel land speed record later this year.

"It's amazing to think that an engine originally produced for tractors should become a possible world beater," he said.

"The Max reached 201mph on Sunday and, although we're not aiming for more than 190mph today, we believe it can do 235mph. The eventual aim is 300mph."

A full squad from JCB – aka J C Bamford Tractors of Cheshire – had been at Wittering over the weekend carrying out testing, revving and trials before Monday's double run in the full glare of publicity.

As the clutch of Press and TV crews gathered respectfully by the runway, the 600hp Max first completed a single supercharged practice sprint – accompanied, at a decent distance, by a small fleet of official cars – before tackling the serious business of two straight, timed runs.

First it appeared in the hazy distance like an avenging yellow torpedo. Then, slowly and steadily, it gathered momentum before whooshing past the onlookers at midpoint on the runway in seconds and racing into the distance.

The first official run recorded 181mph, but by the time its braking red parachute had sprouted for the last time to slow its speed the Max had comfortably clocked 190mph. It was a happy average.

"We're content with the way things went today," said Andy. "The weather was ideal and, apart from a half-hour hold-up when we changed electronic sensors after the trial run, it all went well."

The project is being wholly financed by JCB, with a design team under the aegis of former Rolls-Royce Cars doyen Dr Tim Leverton.






JCB Dieselmax Arrives In US - Mon 07 Aug 06


The JCB Dieselmax team arrived in Utah two weeks before its scheduled attempt on the World Diesel Land Speed Record. The move across the Atlantic was in itself a huge operation, since all the kit - including the car itself, which had to be completely dismantled - accounted for 20% of the capacity of a Boeing 747 cargo plane.



Archive News: 300mph JCB goes for land-speed record - 20 Apr 06


Construction-equipment maker JCB intends to break a land-speed record: a specially-built aerodynamic racer, featuring two 750bhp JCB444 diesel engines - one for each set of wheels - will take part in high-speed runs at the Bonneville Salt Flats later this summer.

The team, led by former record-holder Richard Noble and including current fastest man on earth Andy Green, is aiming for 300mph. This is some way off the 736.035mph achieved by Green in ThrustSSC in 1997, but would smash the current record (235.756mph) set for diesel-powered vehicles back in 1973.


JCB's chairman Sir Anthony Bamford said: 'I am passionate about the importance of engineering excellence to Britain and I see using the JCB engine for this record attempt as a fantastic way of showcasing what British engineers can do. The JCB444 has been acknowledged as a remarkable piece of engineering and this programme to build the world's fastest diesel-powered automobile is precisely the sort of technical challenge we should rise to.'

Green added: 'We will be following in the tradition of British record-breakers by running at the sport's spiritual home, the remarkable Bonneville Salt Flats. I am really looking forward to driving another British entry in the "300mph Club", and a diesel-engined, wheel-driven one at that.'






JCB digger pushing the Dieselmax


300mph digger gets shove from another JCB



This was no ordinary JCB — the Diesel Max streamliner is twice as fast as an F1 car and powered by two JCB digger engines.


And the 201mph recorded this week was the Diesel Max just warming up. In just over two weeks, JCB intend to hit 300mph to set a new world speed record for a diesel-powered vehicle.


The record attempt will be at the famous Bonneville Salt Flats in Arizona but our warm-up was, fittingly, on a runway at RAF Wittering normally used by Harrier jets.


When the JCB Diesel Max was in full flight it looked like a bright-yellow missile that would give even a Harrier a run for its money.


My role in helping the Diesel Max on the way to the record was courtesy of a large push up its rear end by me in a ten-ton JCB Fastrac tractor. In truth, I was only allowed to drive the Fastrac into place behind the Diesel Max. I then moved into the passenger seat next to JCB’s top test driver, Colin Bond.


JCB were understandably nervous my foot might slip and I might push the Fastrac too hard into the Max. As it is a one-off that cost several million pounds to develop, I happily agreed to stand down, especially as the expert Colin told me he was still “nervous” at doing the push.




JCB ... stands for Just Can't Believe it!



The Diesel Max needs a gentle push-start from the Fastrac to just over 30mph before the driver, Wing Commander Andy Green, engages the F1-style paddle gearshift and blasts the fastest JCB ever down the runway under its own power.


And Green was the perfect man to have behind the wheel because he is already the fastest man on Earth.  Green flies Tornado F3 jets but on October 15, 1997, he became the first and only man ever to drive at supersonic speeds when he averaged 763.035mph in Thrust SSC to set the world’s land speed record in Nevada.


He said: “I’m really looking forward to driving another British entry into the 300mph club. “Driving the Diesel Max gives me an opportunity to stretch myself at speed, especially as it’s a diesel — and a JCB.


“This week’s trial runs went even better than expected — it handles superbly at high speed. We’ve hit 200mph and haven’t even opened it up fully yet.” I’m confident about our attempt at the record and there is no reason why we shouldn’t do it.”

But Green is quick to point out that the 300mph record attempt will face problems that are out of the team’s control — like going on a salt lake in 40°C temperatures and high crosswinds. But after passing 200mph this week Green was clearly delighted and still looked as cool as a cucumber, more like someone who had just enjoyed a Sunday afternoon drive


Witnessing the slim Diesel Max surge down the runway from the cab of the Fastrac was one of the most spectacular and bizarre sights I’ve ever experienced.




Fastest man on Earth ... Andy Green


Watching the bright red parachutes burst out of the back to help the brakes bring it to a halt gave a sudden reminder of just how fast the JCB was traveling and how much faster it will be on its record attempt. The man behind the record bid is JCB chairman Sir Anthony Bamford, who has masterminded the firm’s rise to becoming an international success story.


Sir Anthony sees the record run as an opportunity to showcase the excellence of the firm’s diesel engine. He said: “I am passionate about the importance of engineering excellence to Britain and I see using the JCB engine for this record attempt as a fantastic way of showcasing what British engineers can do.


“It has always been a family tradition that the way to make progress is to push the boundaries. I believe that building the world’s fastest diesel-powered automobile is precisely the sort of challenge that we should rise to.”


If Andy Green smashes the record later this month it will be a red letter day for JCB and British engineering — proving we’re still capable of setting the pace in the motoring world.




Not so mellow yellow ... hitting 201mph during warm up





THE Diesel Max is more than 27ft long and weighs 2.7 tons.


POWER: Two 750bhp turbo-charged JCB diesel engines at the front and back driven through two six-speed gearboxes. A radiator would have meant too much drag, so the cooling system is designed around a 44 gallon water-and-ice tank.


TYRES: 23x15 racing tyres – aeroplane tyres were tested but their performance was deemed too unpredictable.


BRAKES: It has a dual circuit, triple-braking system – oh, and parachutes.


STEERING: Conventional rack-and-pinion system to the front wheels but no power assistance.


TOP SPEED: 300mph plus.


ECONOMY: Don’t ask.






Push-start ... Diesel Max is nudged into place



20 April 2006


JCB today unveiled the JCB DIESELMAX vehicle with which it aims to break the world land speed record for a diesel powered automobile in August 2006 at the Bonneville Salt Flats, Utah.  Powered by a pair of advanced 4-cylinder, 5-litre JCB444-LSR diesels, developed with the support of Ricardo, the JCB DIESELMAX boasts the world’s highest specific power diesel engines used in any automobile application


Ricardo is proud to have been selected by JCB as the engine development partner for the JCB DIESELMAX vehicle as well as providing support to the programme. In addition to its advanced diesel engineering expertise, Ricardo applied its state-of-the-art powertrain computer aided engineering software to the task of assisting JCB in the development of the advanced JCB444-LSR engines which power the JCB DIESELMAX.  Ricardo was also able to draw upon extensive knowledge and experience of the engine architecture which forms the basis of the JCB444-LSR engines as a result of its previous role as concept engineering partner on the production JCB444 engine from which the land speed record engines are developed and with which they share many components. 


The resulting JCB444-LSR engines exhibit many of the technologies which are likely to form the basis of the next generation of high performance, low-emissions diesel engines in both automotive as well as heavy-duty applications. The results are truly impressive and the headline figures speak for themselves: with each delivering peak power of 750hp and torque of 1500Nm the engines are over five times the power of the production version and at 150hp/litre, they exceed even motorsports applications as the world’s highest specific power diesels.  At the same time the JCB DIESELMAX engines retain excellent fuel efficiency and very low emissions through the use of advanced combustion control and diesel particulate filter technology. 





Diesel Max, l'auto più veloce del mondo

Il pilota Andy Green tenterà di superare il record dei 482 km l'ora


Il pilota Andy Green a fianco a Diesel Max


Correrà sulla pista statunitense di Bonneville, nello Utah, con un obiettivo: puntare al record di 482 chilometri l'ora. È la Diesel Max, l'auto più veloce del mondo studiata per volare anche a 500 km l'ora. A guidarla, sarà ovviamente un uomo da primato, Andy Green, matematico, ex colonnello della Raf e vero top gun dei Phantom e dei Tornado.

Grazie alla sua forma allungata, questa auto da record assoluto si è già conquistata il nome di «siluro» e, causa appunto la sua lunghezza, non è potuta entrare nella galleria del vento per i test d'obbligo. Ma i tecnici non si sono persi d'animo. Così, per verificare se la struttura era all'altezza del primato che il veicolo vuole conquistare, hanno inventato da capo a piedi un software tutto per lei.

A realizzare la freccia delle piste per quattro ruote è stata la britannica Jcb, uno dei principali costruttori mondiali di macchineda cantiere e per l'edilizia che questa volta, sottolinea il periodico diretto da Jacopo Loredan, ha costruito un veicolo battezzato già «il diesel più veloce del pianeta», capace di toccare le 300 miglia orarie, cioè 482 km/h.

L'auto da record sfrutta non uno ma ben due motori a quattro cilindri da 750 cavalli ciascuno e, dalle motoscavatrici alla formula uno da guinness, l'azienda britannica ha realizzato un veicolo che, nonostante le sue prestazioni, sviluppo appena 2500 giri. Nel suo serbatoio la Jcb Diesel Max ha solo 9 litri di carburante, ma usa 250 chili di ghiaccio al posto del radiatore.

Il pilota Andy Green, che porterà l'auto sul podio dei primati mondiali, è il primo uomo ad aver sfondato nel 1997 il muro del suono a bordo di un veicolo lanciato nel deserto di Black Rock, in Nevada, alla folle velocità di 1.227,986 chilometri l'ora. Per battere il nuovo record con «il siluro», Green dovrà affrontare un tratto di 9 miglia di pista pari a 14,5 chilometri per due volte in un'ora, tentando così di superare il precedente record che ha visto la stessa auto lanciatoa a 379,413 chilometri l'ora.

La sfida è prevista per il prossimo mese e, siccome l'auto ha un telaio da record lungo ben 9 metri che non si può smontare, Green è pronto a partire per States con ben 27 tra ingegneri e meccanici, carichi di 20 tonnellate di attrezzature.
