Future of Gasoline Engines

SAE Technical Paper Series, 1972
<div class="htmlview paragraph">The present spark ignition, reciprocating piston, gasoline engine is examined against the basic requirements for an automotive powerplant. The important requirement of emission control is shown to affect these basic requirements. The emission potential of this engine and the prospect of reducing its emissions to an

Run-on in Gasoline Engines

Proceedings of the Institution of Mechanical Engineers: Automobile Division, 1968
When the ignition of a car engine is switched off, the engine normally comes to rest within a few revolutions but, occasionally, it may continue to fire erratically for a few seconds or longer. This phenomenon is known as run-on and, for the majority of European engines, is the result of spontaneous ignition of the fuel-air mixture in the combustion ...

The future of gasoline engines

2015
Both the future test cycles and more fuel-efficient transmission and electrification concepts are shifting the ICE operation towards higher engine loads. Whereas in the past, FE measures with Gasoline Engines were mainly concentrated on the reduction of throttle losses, in future the extension of the sweet spot area becomes decisive.

Combustion in Gasoline Engines

1990
The rate of burning in the cylinder exercises considerable influence upon the power and efficiency of the engine. Combustion should occur close to top centre and be rapid enough to utilize to the fullest possible extent the maximum compression, and yet not be so rapid as to induce strong shock waves in the gas or intolerable impact loadings on bearings

Control of thermal ignition in gasoline engines

Proceedings of the 2005, American Control Conference, 2005., 2005
In this paper a model based controller is designed to regulate the crank angle of 50% fuel burned (CA50) and the air to fuel ratio (AFR) in the exhaust manifold of a gasoline engine during fuel step changes. The regulation of the combustion timing is based on manipulating the charge temperature through the internal and external dilutions which are ...

Control of gasoline engines

2014
“Motronic” is the name of an engine-management system that facilitates open- and closed-loop control of gasoline engines within a single control unit. There are Motronic variants for engines with intake-manifold injection (ME Motronic) and for gasoline direct injection (DI Motronic).

Carcinogenic potential of gasoline and diesel engine oils

Fundamental and Applied Toxicology, 1989
Used gasoline engine oils are carcinogenic in mouse skin and mutagenic in Salmonella. The toxicity of fresh gasoline engine oils and that of fresh and used diesel engine oils are less well defined. The present studies examined the dermal carcinogenic potential of a series of fresh and used oils from both gasoline and diesel engines.
