The PressureSense Glow Plug combines a miniature fiber optic-based cylinder pressure sensor with the automotive glow plug. The 1.7mm diameter sensor is sealed inside a glow plug heater and the sensor signal conditioner is encapsulated into a “smart connector”. The sensor operates on the proven principle of light intensity changes, transmitted by two optical fibers, upon reflection from a deflec...

conventional compression ignition (ci) engines are known for their high thermal efficiency compared to spark ignited (si) engines. gasoline because of its higher ignition delay has much lower soot emission in comparison with diesel fuel. using double injection strategy reduces the maximum heat release rate that leads to nox emission reduction. in this paper, a numerical study of a gasoline fuel...

Abstract Late intake valve closing (LIVC) Miller cycle was used on a highly-intensified single cylinder diesel engine to reduce the maximum combustion pressure and temperature. Three cams with three LIVC timings were designed tested bench. The gas exchange process of investigated by 1-D simulation model which calibrated experimental data. analysis conducted at constant speed 3600 r/min two IMEP...

Ozone (O 3 ) was introduced into the intake air to control ignition in a gasoline compression (GCI) engine. An early fuel injection at ?68 °CA ATDC adopted mix with reactive O-radicals decomposed from O , before reduction of due their recombination would take place. The second implemented near top dead center optimize profile heat release rate. engine experiments were performed around indicated...

Gaseous fuels, e.g., natural gas, biogas, have several advantages over liquid fuels owing to their favorable physical and chemical properties, lower carbon numbers in the fuel composition no issues regarding evaporation. The present study investigated compressed gas (CNG) port injection (PFI) direct (DI) systems compared gasoline (GDI) cases a spark ignition (SI) naturally aspirated single cyli...

An investigation into the exhaust emissions of carcinogenic polycyclic aromatic hydrocarbons (PAHs) from a diesel engine was reported. The study is reinforced by experimental results obtained tube reactor aimed at examining PAH formation processes these fuels. paper cantered on 16 priority PAHs suggested United States Environmental Protection Agency (US-EPA). These were produced burning convent...

A study was conducted to determine the ability of neural networks to extract high level control information from cylinder pressure data. Various experiments were performed us ing neural networks for pattern recognition on a series of data files consist ing of cylinder pressure versus crank angle. The goal of these experiments was to estimate spark timing based on the cylinder pressure signature...

This study aims at developing a framework to address marine engines utilising based on first-principles. follows four distinct stages, former two including engine digital-twin set up by customising required thermodynamic model...

The addition of hydrogen peroxide and steam to a hydrogen-fuelled HCCI engine was investigated at various fuel lean conditions (ϕeff = 0.2–0.6) compression ratios (15–20) using 0-dimensional numerical model. use as an ignition promoter demonstrated increased IMEP (16%–39%), thermal efficiency (up 2%), reduced NOx (50%–76%) when compared the conventional method intake charge heating. When used p...
