Performance of Homogenous Charge Compression Ignition (HCCI) Engine with Premixed Methane/ Air Supported by DME for Electrical Power Generation Application

performance of homogenous charge compression ignition (hcci) engine with premixed methane/ air supported by dme for electrical power generation application

homogenous charge compression ignition (hcci) is a mode of combustion in ic engines in which premixed fuel and air are ignited spontaneously. there is a belief that hcci engines have a great potential to improve fuel consumption and reduce nox emissions. in this study, a single zone, zero dimensional, thermo-kinetic model has been developed and a computer program with matlab software is used to...

Homogenous Charge Compression Ignition (HCCI) Engines

Control of Homogeneous Charge Compression (HCCI) Ignition Engine Dynamics

The Homogeneous Charge Compression Ignition (HCCI) combustion concept lacks direct ignition timing control, instead the auto ignition depends on the operating condition. Since auto ignition of a homogeneous mixture is very sensitive to operating conditions, a fast combustion timing control is necessary for reliable operation. Hence, feedback is needed and the crank angle of 50% burnt (CA50) has...

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...

بررسی جامع عوامل موثر بر زمان شروع احتراق در یک موتور اشتعال تراکمی سوخت همگن با سوخت متان

Homogenous charge compression ignition engine is a promising idea for reducing fuel consumption and engine emissions. As homogenous mixture of air and fuel is compressed until auto-ignition occurs in HCCI engines, therefore start of combustion is strongly related to chemical kinetic mechanism of fuel oxidation. In this paper, a thermodynamic single-zone model including detailed chemical kine...

Formaldehyde for the Premixed Compression-ignition Engine - an Additive for Ignition-timing Control -

Lean fuel/air mixtures with various fuel/fuel ratios between methane and n-butane were supplied to a premixed compression-ignition engine (i.e. homogeneous charge compression ignition engine, HCCI) with or without supplementary gaseous formaldehyde induction as an ignition controlling additive. In the no additive case the methane and butane function as the two fuels in the high/low-octane two-f...
