Natural gas is promising alternative fuel to meet strict engine emission regulations in many
countries. Compressed natural gas (CNG) has long been used in stationary engines, but the …

Direct injection (DI) of natural gas (NG) at high pressure conditions has emerged as a high-
potential strategy for improving SI engine performance. Besides, DI allows an increase in the …

This research investigated the combustion process of an AVL Model LEF/Volvo 5312 single
cylinder engine configured to simulate the operation of a heavy-duty spark ignition (SI) …

An experimental investigation and a burning-rate analysis have been performed on a
production 1.4 liter compressed natural gas (CNG) engine fueled with methane-hydrogen …

An experimental investigation of fuel consumption, exhaust emissions and heat release was
performed on a prototype 1.2 liter 4 cylinder turbocharged CNG engine, which has been …

A new three-step anaerobic sequencing batch reactor (3S-ASBR) was developed to
enhance methane productivity and energy yield by varying the reactor volumetric and …

The heat release analysis has proved to be a powerful diagnostic tool for the analysis of the
combustion process in spark ignition engines. Still, a fine tuning of the heat transfer …

Most of the energy consumed in today's mobility industry is derived from fossil fuels. The
demand for clean, renewable and affordable alternative energy is forcing the automotive …

We investigated the effects of the fuel injection timing—both for early and late injection—in
conjunction with the throttle opening ratio on the fuel-air mixing characteristics, engine …

In this work a quasi-dimensional multi-zone combustion diagnostic tool for homogeneous
charge Spark Ignition (SI) engines is analytically developed for the evaluation of heat …
