In this chapter, the engine control structure for spark ignition (SI) and compression ignition (CI) engines is examined. First, a general overview of engine control is given. A suitable architecture is presented which can be used to handle the demanding requirements on process control. By the ...
Compression ratio for the fuel: In the case of SI engines, the compression ratio of the fuel is in the range of 6 to 10 depending on the size of the engine and the power to be produced. In CI engines, the compression ratio for air is 16 to 20. The high compression...
Natural gas is a fossil fuel that has been used and investigated extensively for use in spark-ignition (SI) and compression-ignition (CI) engines. Compared with conventional gasoline engines, SI engines using natural gas can run at higher compression ratios, thus producing higher thermal efficiencie...

Powertrain Blockset / Propulsion / Combustion Engines Vehicle Dynamics Blockset / Powertrain / Propulsion Description TheMapped CI Engineblock implements a mapped compression-ignition (CI) engine model using power, air mass flow, fuel flow, exhaust temperature, efficiency, and emission performance lookup ...
The engine was operated at ¾ throttle valve opening position and 2500 rpm atλ values of 0.996, 1.089, 1.216 and 1.341. According to the authors, the proposed γ model was accurate for SI engines when λ was approximately 1.1. The derived γ model of Ceviz and Kaymaz [1] accounted for...
Combustion-Related Emissions in CI Engines 来自 ResearchGate 喜欢 0 阅读量: 44 作者: G Hawley,J. 摘要: For many years, particularly in the United States, diesel engines have had a reputa-tion of giving poor performance and producing black smoke, an unpleasant odor, and considerable noise. ...
