SI Engine Controls and Mean Value Engine Modelling

SAE Technical Paper Series, 1991
<div class="htmlview paragraph">Many existing classical electronic control systems (speed-throttle, speed-density, MAF (mass air flow)) are based on quasistatic engine models and static measured engine maps. They are thus time consuming to adapt to new engine types, are sensitive to dynamic sensor errors and in general have undesirable dynamic ...

Effect of exhaust gas recirculation and hydrogen direct injection on combustion and emission characteristics of a n-butanol SI engine

, 2020
The n-butanol as a clear and renewable biofuel is considered an ideal alternative fuel for SI engines. Hydrogen as a partial alternative fuel can improve the combustion and emissions of SI engine because of its advantages of low ignition energy, fast ...

Nonlinear observer design for turbocharger in a SI engine

2013 American Control Conference, 2013
Estimation of major turbocharger variables is essential for proper control and monitoring of a turbocharged engine. This work presents a novel algorithm to estimate turbocharger rotator speed, air temperature downstream a compressor and flow rate over the compressor using mean value models of engine subsystems.

The Effects of Crevices on the Engine-Out Hydrocarbon Emissions in SI Engines

SAE Technical Paper Series, 1994
<div class="htmlview paragraph">To understand the effects of crevices on the engine-out hydrocarbon emissions, a series of engine experiments was carried out with different piston crevice volumes and with simulated head gasket crevices. The engine-out HC level was found to be modestly sensitive to the piston crevice size in both the warmed-up and

Investigation into SI engine performance characteristics and emissions fuelled with ethanol/butanol-gasoline blends

, 2019
The detrimental environmental impacts of the use of conventional fuels, both gasoline and diesel, have spurred researchers to seek alternative fuels that minimize these environmental impacts and risks.
