Can Hydrogen Injection save the diesel engine?

The greatest automotive story this century has been the “Dieselgate” conspiracy. Not only has it brought down the established regime at VW, but it’s shaken the very foundation of diesel powered transportation. VW has already started rolling out a fix in Europe, which many of us are sceptical about, but are still “negotiating” with legislators […]

Ignition systems spark new interest in ICE’s.

The new generation of downsized turbocharged engines require more than a spark generated at the right time to initiate combustion: Some mixtures exceed stoichiometric ratios and in theory should not even combust. The modern ignition system has evolved from a purely mechanical switch used to charge the coil, to engine-management controlled, electronic switching circuits. A few […]

BMW use water injection in the Motogp Safety car

New BMW 3 cylinder runs on water!

Well that’s not quite correct: The BMW Group has tried enhancing the capabilities of conventional engine technology using direct water injection for turbocharged petrol engines. Although this was used for many years by Porsche Turbo “hot-rodders” BMW are about to introduce this into series production. The controlled water injection into the engine cylinders produces a cooling […]

Exploded view of a catalytic convertor

Do Catalytic Converters still need Platinum?

  Ever since the work carried out by people such as Robert C. Stempel in the 1970’s, automotive catalytic convertors have used precious metals such as platinum, palladium and rhodium to promote the reaction of exhaust gases; by so doing converting nitrous oxides, carbon monoxide and unburned hydrocarbons into nitrogen gas, carbon dioxide and water. […]

Are Hydrogen fuel-cell cars being overlooked?

Despite Volkswagen’s embarrassing Dieselgate exploits there’s no doubt that the motor industry is serious about cleaning up its act. And supported by government funding, such as Britain’s recently announced grant of £400 million to promote plugin hybrids electric vehicles show signs of making a difference. However in the 2011 State of the Union, President Obama […]

The real world of emissions testing.

  Currently, fuel consumption and carbon dioxide emission values for new cars in Europe are determined using a type-approval process, which involves testing vehicles under laboratory conditions. In the automotive industry laboratory testing is common place for a number of reasons, including standardization and repeatability. On face value this would seem to be a good […]
