Measurement and analysis of engine starts in SI engines
MTZ worldwide, 2006Just 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

Ammonia as a Fuel for SI Engine
SAE Technical Paper Series, 2003<div class="htmlview paragraph">Ammonia is a potential alternative fuel that was indeed put into use in Belgium in World War II due to the extreme shortage of diesel. It has a high heating value per unit volume (1.16 × 10<sup>7</sup> kJ/m<sup>3</sup>) and its combustion products can be as or more environment-friendly ...

An Improved Model for SI Engines
ASME 2004 Internal Combustion Engine Division Fall Technical Conference, 2004In this paper an improved mathematical model of spark ignition engines is presented. The model is derived based on a combination of thermodynamically relations and dynamical characteristics of engines. The geometrical parameters of the engine, valves and spark timing, air to fuel ratio, specific fuel consumption and engine operational conditions are ...

International Journal of Exergy, 2008
In this study, exergy (availability) analysis of a Spark Ignition (SI) engine has been performed theoretically during compression, combustion and expansion processes of the engine cycle. For this purpose, a thermodynamic-based engine cycle model is developed without considering the geometric features of fluid motion.

Engine Variables Affecting the SI Engine Knock
Volume 2: Large-Bore Engines, Fuel Effects, Homogeneous Charge Compression Ignition, Engine Performance and Simulation, 2001Abstract To program the automatic performance control loops of the modern cars at the design stage, numerical result of engine variables effecting knock intensity is the most important tool. Although general aspects of the effect of engine operating conditions on knock have been studied in previous investigations, precise numerical ...

Basics of the gasoline (SI) engine
2014The gasoline or spark-ignition (SI) internalcombustion engine uses the Otto cycle and externally supplied ignition. It burns an air/fuel mixture and in the process converts the chemical energy in the fuel into kinetic energy.
