Downsizing of SI Engines by Turbo-Charging

Volume 4: Fatigue and Fracture, Heat Transfer, Internal Combustion Engines, Manufacturing, and Technology and Society, 2006
During most of the operating conditions occurring on a vehicle driving cycle, a reciprocating IC engine works at low load and low speed, with poor fuel efficiency. In this regard downsizing appears as a major way of improving fuel consumption of Spark Ignition Engines.

Advanced Engine Misfire Detection for SI-Engines

SAE Technical Paper Series, 1997
<div class="htmlview paragraph">This paper presents a system concept for detecting combustion misfire. The relevant research grew out of the more stringent requirements for On-Board Diagnostic systems (OBDII) mandated by the California Air Resources Board (CARB), effective as of model year 1997 onward. The system concept is based on evaluation of

Measurement and analysis of engine starts in SI engines

MTZ worldwide, 2006
Just like the scientist uses his microscope to study tiny pathogens as the cause of major epidemics, engineers developing vehicle engines have to study a growing number of engine process details. Although modern engine management systems are capable of storing ever more complex models for engine control, checking and coordinating these models is ...

Variable compression in SI engines

SAE Technical Paper Series, 2001
<div class="htmlview paragraph">Downsizing is an effective way to further improve the efficiency of SI engines. To make most of this concept, the compression ratio has to be adjusted during engine operation. Thus, the efficiency disadvantages during part load can be eliminated. A fuel consumption reduction of up to 30% can be realized compared to

Experimental and numerical investigation of the effects of low-pressure, high-pressure and internal EGR configurations on the performance, combustion and emission characteristics in a hydrogen-enriched heavy-duty lean-burn natural gas SI engine

Energy Conversion and Management, 2019
In this study, a detailed 1D simulation model of the hydrogen-enriched natural gas SI engine was built according to realistic engine layout in the lab with practical boundary conditions, and validated against the experimental data.

Comparative study on combustion and emission characteristics of methanol/hydrogen, ethanol/hydrogen and methane/hydrogen blends in high compression ratio SI engine

Fuel, 2020
Currently, alternative energy sources such as hydrogen and alcohol are increasingly used in IC engines. There is a gap in the literature of both experimental and numerical studies considering hydrogen addition in a high compression ratio engine (using ...

Numerical investigation of water injection quantity and water injection timing on the thermodynamics, combustion and emissions in a hydrogen enriched lean-burn natural gas SI engine

International journal of hydrogen energy, 2020
Water direct injection into the cylinder is one of effective ways to suppress the combustion rate and knocking combustion in turbocharged SI engine. In this study, a detailed one-dimensional model coupled with the water direct injection was built by ...
