In 1912 he stated: “The diesel engine can be fed with vegetable oils and would help considerably in the development of agriculture of the countries which use it” and that “The use of vegetable oils for engine fuels may seem insignificant today. But such oils may become in course of time as important as petroleum and the coal tar products of the present time.”
A brief history of diesel begins with Rudolf Diesel the inventor. Rudolf Diesel was born in 1858 in Paris, France and educated at Munich Polytechnic. After graduation he became a refrigerator engineer, but didn’t enjoy it as much as his true love of engine design. Continue reading An amazingly timely quote by Rudolph diesel.

I’ve sampled quite a few different diesel Peugeot variants and up until this point, I was convinced they had it right. They hit the perfect mix between economy and power – that was until I drove the new 207 HDi Touring.
In theory, the car works very well. It’s spacious enough to fit a small family and its belongings, and on paper it’s frugal enough to keep the finance manager happy at the end of the month. But one area it lacks – and quite noticeably – is when the car is loaded full of people and expected to perform. At certain times, it felt as though Peugeot had focused on getting the best fuel efficiency out of this engine, opposed to building it for drivability.
After loading five people into the car with some luggage, the 40-degree day required the added assistance of air conditioning. Coming onto the freeway onramp, I progressively increased the throttle from a standing start and received next to nothing in return. The lack of power was daunting at times. Plenty of forethought was required before even attempting any overtaking manoeuvres or pulling out in busy traffic.
In a way, the engine shouldn’t be the sole determinant of a car’s abilities. But, in this case – seeing as it’s built as a family car – the engine is the car’s Achilles heel. Continue reading CarAdvice.com.au reviews the 2008 Peugeot 207 Touring HDi
The Toyota hybrid is hailed as an eco-paragon, so how does it fare against a big BMW?
To find out we set a challenge: to drive a Prius to Geneva using motorways and town driving. The direct route is 460 miles but we drove almost 100 miles further to give the Prius the advantage of running in urban conditions where its petrol-electric drivetrain comes into its own.
We took along a conventionally powered car – a diesel BMW executive saloon – for comparison and drove both cars an identical number of miles (545). Continue reading Toyota Prius Vs BMW 520d.

There are the odd examples of why hybrids are under the pump in certain quarters.
Resale and battery issues aside, there has always been much conjecture about the virtues, environmental or otherwise about petrol/electric hybrids, particularly as there are some small diesel cars around these days that weaken the case for buying a hybrid for reasons of fuel economy.
Prime case is Citroen’s C3 HDi. There is now a nifty 1.6-litre diesel sitting pretty in the nose of the cute C3 — and it delivers quite a bit of punch once the revs rise beyond 2000rpm. Continue reading Citroen C3 HDi: Quick test

New Ford Australia chief Bill Osborne says he would have made the FG diesel variant had he been at the helm earlier.
Osborne, who took over two months ago, confirms a diesel engine, almost certainly a reworked version of the PSA group’s unit used by Peugeot, Jaguar and Land Rover, will be dropped into Falcons and Territorys in 2010. Continue reading Diesel FG Falcon on the cards.

World’s Smallest Diesel
The DaimlerChrysler Smart FourTwo features the world’s smallest direct injection diesel engine. The 800c turbo 3-cylinder develops 33kW at just 3800 rpm.
Over the European fuel test cycle, the FourTwo diesel engine gives fuel economy of 3.3 litres/100km and emits just 88 grams of CO2 per kilometre.
Fuel injection pressure is 1600 Bar and 7-hole injectors are used. A large amount of exhaust gas is recirculated – as much as 60 per cent of exhaust gases are cooled and then returned to the combustion chambers.
As is the case with other current direct injection engines, the electronically-controlled diesel uses a pilot injection squirt that ignites and preheats the cylinder, reducing noise emissions.
A tiny turbo is fitted. The compressor has a diameter of only 33mm but it rotates at up to 280,000 rpm. A maximum boost pressure of 1.2 Bar is used. The small turbo and diesel configuration allows for low-rpm torque development – 85Nm is available at just 1500 rpm!
However, the 770kg car is abysmally slow – 100 km/h comes up in a fraction under 20 seconds and top speed is only 135 km/h. Continue reading Little diesels.

It is mid-morning on 23rd August 2006 and Ricardo’s Matt Beasley, in common with his team of diesel engineers, feels a sense of sheer elation. Together with colleagues at Ricardo and JCB, they had successfully completed a remarkable engineering program that had transformed the existing, co-developed JCB444 engine from a sturdy construction equipment unit into the world’s highest specific power automotive diesel – the JCB444-LSR. It was with this engine that the JCB Dieselmax had just broken the Bonneville SpeedWeek record for a diesel car and set two new FIA certified international land speed records in the space of just six days.
