Gasoline direct injection (GDI) continues to be a weapon in the technology armoury of automakers in their fight to reduce CO2. Manufacturers believe that homogeneous applications of GDI will be ...

SAE Transactions, Vol. 96, Section 4: RECIPROCATING ENGINES–SPARK IGNITION AND DIESEL (1987), pp. 614-623 (10 pages) A single-cylinder, variable–compression ratio, direct–injection diesel engine was ...

High pressure common rail system can precisely control the injection time and injection pressure to improve the thermal efficiency of the engine. The injection characteristics of the system can affect ...

Delphi is developing an engine fuel injection technology that could improve the fuel economy of gas-powered cars by 50 percent, potentially rivalling the performance of hybrid vehicles at less cost.

What many consider the Holy Grail of combustion technology is one step closer to prime time. In the race to field energy-efficient vehicles, don’t count out internal combustion technology just yet. GM ...

The goal of Hyundai's engine technology, which the company calls Gasoline Direct Injection Compression Ignition (GDCI), is to return the fuel economy of a diesel but with the higher performance, ...

50% fuel economy over current gasoline engines. It operates kind of like a diesel engine. The one demonstrated is a single cylinder engine but they are working on multi-cylinder engines. Still... if ...

Westport Fuel Systems has developed a new fuel system that can burn hydrogen in heavy-duty internal combustion truck engines. The new H2 HPDI fuel system is based on Westport’s HPDI fuel system ...

Direct injection, as the name suggests, refers to a type of fuel system which introduces fuel directly into an engine's combustion chambers. This differentiates it from conventional injection systems ...

Any diesel-engine manufacturer that confidently claims it produces an oil-burner with the “world’s lowest compression ratio,” will no doubt draw the immediate attention of inquisitive enthusiasts, ...
