In the present paper, a model-based controller of engine torque and engine-out Nitrogen oxide (NOx) emissions, which was previously developed tested by means offline simulations, has been validated on FPT F1C 3.0 L diesel rapid prototyping. With reference to previous version, new NOx model implemented improve robustness in terms prediction. The experimental tests have confirmed basic functional...

A cost effective, low maintenance generator brake is proposed using recent developments in thick film, metal oxide resistors. The brake has very low resistance, and virtually no inductance, allowing its use &ring a fault to slow a generator’s acceleration. Simulation results using the 39 Bus New England system show that placing brakes at each machine dramatically increases the global stability ...

Vehicle braking system is considered as one of the most fundamental safety-critical systems in modern vehicles as its main purpose is to stop or decelerate the vehicle. The frictional heat generated during braking application can cause numerous negative effects on the brake assembly such as brake fade, premature wear, thermal cracks and disc thickness variation (DTV). In the past, surface rough...

The tightening of diesel pollutant emission regulations has made Internal Combustion Engine (ICE) management through steady-state maps obsolete. To overcome the map’s scarce performance and efficiently manage engine, control systems must cope with ICE transient operations, coupling between its subsystem dynamics, tradeoff different requirements. work demonstrates effectiveness a reference gener...

Investigations were carried out to study the exhaust emissions from high grade low heat rejection (LHR) diesel engine consisting of air gap insulated piston with 3-mm air gap with superni (an alloy of nickel) crown, air gap insulated liner with superni insert and ceramic coated cylinder head with normal temperature condition of crude jatropha oil and carbureted alcohol (ethanol / methanol) with...

Due to the difficulty directly study ammonia, present work investigated engine performance of lean iso-octane/air mixture approximate ammonia combustion behaviour. The was conducted using a single cylinder modified diesel that features spark plug and glow in sub-chamber. investigations varied speeds (1000 1500 RPM), voltages (6 10 volts), excess air ratios (1.4 1.8), ignition timings (-2 -5 °BT...

In this study, we investigated the effects of canola oil biodiesel (BD) to improve combustion and exhaust emissions in a common rail direct injection (DI) diesel engine using BD fuel blended with diesel. Experiments were conducted with BD blend amounts of 10%, 20%, and 30% on a volume basis under various engine speeds. As the BD blend ratio increased, the combustion pressure and indicated mean ...

OBJECTIVE To reanalyse data on the lung content of asbestos fibres among brake mechanics. METHODS I re-analysed data published by Butnor, Roggli and colleagues on the lung content of chrysotile and tremolite asbestos fibres among brake mechanics and controls. Statistics of the distributions were estimated by maximum likelihood to accommodate observations below the detection limit. Mean concen...
