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’s on the outs in Europe, and EVs aren’t ready for prime time. Skyactiv-X seems, at this juncture, a hedge bet against both aspects. EV infrastructure lags massively behind our petroleum ...

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 ...

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 ...

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, ...

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 ...

SAE International Journal of Fuels and Lubricants, Vol. 7, No. 2 (June 2014), pp. 412-426 (15 pages) ABSTRACT In the context of stringent future emission standards as well as the need to reduce ...

Diesels engines modified to run on gasoline and a gasoline engine that doesn’t use spark plugs to initiate combustion? Alt fuel and fuel economy regs may own the spotlight, Roberts writes, but there’s ...

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 ...

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 ...
