Compression Ratio Effect on Methane HCCI Combustion

Homogeneous Charge Compression Ignition (HCCI) Combustion Engine- A Review

At present, it is highly required from the automobile sector to develop clean technologies with lower fuel consumption for ambient air quality improvement, green house gas reduction and energy security. Furthermore, due to continuously stringent emission legislation and the fast depletion of the primary energy resources, the development of new highly efficient and environment friendly combustio...

Active Combustion Control of Diesel HCCI Engine: Combustion Timing

We propose a model based control strategy to adapt the injection settings according to the air path dynamics on a Diesel HCCI engine. This approach complements existing airpath and fuelpath controllers, and aims at accurately controlling the start of combustion. For that purpose, start of injection is adjusted based on a Knock Integral Model and intake manifold conditions. Experimental results ...

Control-oriented Model of Isooctane Hcci Combustion

A mathematical engine model is developed in this paper to study the operation process in HCCI engines. Isooctane is used as fuel for testing in this model. Two-step reaction mechanisms are implemented to model combustion process and heat transfer process is also included. Results from this model show good correlation with experiment with respect to combustion phasing, pressure rise and peak pre...

Numerical Investigation of the Effect of Cooled EGR on Turbocharger HCCI Engine Performance Fueled with Methane

Effect of Dimethoxy-methane (C3H8O2) on Combustion Characteristics of a Direct Injection Diesel Engine with Variable Compression Ratio, Fuelled with Biodiesel Blends with Diesel (C10.8H18.7)

It is necessary to find a fuel source due to the heavy usage of natural resources. Developing countries have been trying various sources and methods to identify suitable alternative fuel for engines. This paper presents the utilization of Palm Oil Methyl Ester (POME) blends with diesel in Variable Compression Ratio (VCR) diesel engine. The performance and emission characteristics of biodiesel w...
