This study aims to propose an analysis method for resolving the pressure response of a pneumatic brake circuit considering the effect of a transmission pipe. Pneumatic brake systems (PBS) are widely used in commercial vehicles. The pressure response characteristic of the PBS is the key factor affecting braking performance. By using the thermodynamics of a variable-quality system, the pressure r...

A single zone C.I engine model has been developed in an in-house code that would be suitable for conventional diesel as well as for alternative fuel (biodiesels), to predict the pressure and temperature variation along crank angle, work done, mean effective pressure, power output and other engine parameters suitable for biodiesel. The model has been validated with the experimental results. Perf...

The present study focuses on the effect of air-fuel ratio on the performance of four cylinder hydrogen fueled direct injection internal combustion engine. GT-Power was utilized to develop the model for direct injection engine. Air-fuel ratio was varied from rich limit to a lean limit. The rotational speed of the engine was varied from 1250 to 4500 rpm. The acquired results shown that the air fu...

Investigations are carried out to evaluate the performance of a low heat rejection (LHR) diesel engine consisting of different versions such as ceramic coated cylinder head engine-LHR-1; Air gap insulated piston and air gap insulated linerLHR-2; and Ceramic coated cylinder head, air gap insulated piston and air gap insulated liner –LHR-3 with normal temperature condition of linseed oil with var...

Investigations were conducted to evaluate the performance of a two-stroke, single cylinder, spark ignition (SI) engine, with gasohol (80% gasoline and 20% ethanol by volume) having copper coated engine [CCE, copper-(thickness, 300 μ) coated on piston crown, inner side of cylinder head] provided with catalytic converter with different catalysts of sponge iron and manganese ore and compared with ...

Investigations are carried out to evaluate the performance of a low heat rejection (LHR) diesel engine consisting of air gap insulated piston with 3mm air gap, with superni 2/4(an alloy of nickel) crown and air gap insulated liner with superni insert with different operating conditions of crude pongamia oil (CPO) with varied injection pressure and injection timing. Performance parameters of are...

Experiments were conducted to evaluate the performance of a high grade low heat rejection (LHR) diesel engine with air gap insulated piston, air gap insulated liner and ceramic coated cylinder head [ceramic coating of thickness 500 microns was done on inside portion of cylinder head] with different operating conditions [normal temperature and pre-heated temperature] of crude pongamia oil (CPO) ...
