A team of engineers from UNSW Sydney have successfully converted a standard diesel engine to run as a hybrid diesel hydrogen engine. The resulting hybrid reduces CO2 emissions by 85%, and increases output efficiency by around 26%.  The team, led by Professor Shawn Kook, spent some 18 months developing the direct injection dual fuel system. The retrofitted engine runs using 90% hydrogen. Professors Kook believe that the new tech could significantly reduce the emissions from the trucking industry and the...

Anything with a diesel engine -- plane, boat, motorcycle -- can run on diesel, straight vegetable oil or biodiesel.

The present invention relates to the use of at least 120 ppm of a nitrogen-containing detergent as a diesel fuel additive to improve the performance of a diesel engine having a high pressure fuel system.

An exhaust apparatus for a diesel engine rapidly burns an unburned deposit in an upstream exhaust catalyst with heat of a heater. The exhaust apparatus includes a downstream exhaust cleaner, an upstream exhaust catalyst provided in an exhaust passage, upstream of the downstream exhaust cleaner, a heater disposed at an exhaust inlet of the upstream exhaust catalyst, and an engine starter apparatus. A control unit controls the power supply to the heater and an engine start process is performed by the engine starter apparatus. A start command unit is connected to the control unit. When the engine has been stopped and then the start command unit gives the control unit a start command, the control unit powers the heater without performing an engine start process, thereby keeping the engine stopped for a predetermined period of time after the start command has been given, and subsequently performing the engine start process.

Cummins Inc., a major motor vehicle engine company based in Columbus, Ind., will pay a $2.1 million penalty and recall 405 engines under a settlement agreement resolving alleged violations of the Clean Air Act.
