Abstract EN
This experimental part investigates the effect of injection timing on performance and emissions of homogenous mixture compressed natural-gas direct injection.
The engine of 1.6 L capacity, 4 cylinders, spark ignition, and compression ratio of 14 was used.
Performance and emission were recorded under wide-open throttle using an engine control system (Rotronics) and the portable exhaust gas analyser (Kane).
The engine was tested at speed ranging from 1500 revolutions per minute (RPM) to 4000 RPM with 500 RPM increments.
The engine control unit (ECU) was modified using Motec 800.
The injection timings investigated were at the end of injection (EOI) 120 bTDC, 180 bTDC, 300 bTDC, and 360 bTDC.
Results show high brake power, torque, and BMEP with 120 as compared with the other injection timings.
At 4000 RPM the power, torque, and BMEP with 120 were 5% compared to that with 180.
Furthermore, it shows low BSFC and high fuel conversion efficiency with 120.
With 360, the engine produced less CO and CO2 at higher speeds.
