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 ...

Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they ...

A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

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 ...

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, ...

The automotive industry continues to be a hotbed of innovation, with activity driven by factors such as auto-ignition properties of the fuel, fuel concentration, and residual rate, and growing ...

Diesel aircraft engines promise lower fuel burn and cheaper operating costs at a time when every gallon and every kilogram ...

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 ...

Direct injection. Just about every car has it now, and those that don’t probably will in the next few years. It can add power, reduce emissions, and is a big part of why just about everybody is ...
