Abstract:
Numerous combustion strategies have been suggested for compression ignition engines in order to meet the stringent emission regulations with minimal sacrifice in the fuel economy. Premixed charge compression ignition combustion has the potential to reduce the nitrogen oxide emissions and the soot emissions while maintaining a high thermal efficiency and has become the research focus recently. Experiments and simulations were used to study the effects of the injection mode and the injection timing on the premixed charge compression ignition combustion and the emissions in a heavy-duty diesel en

In this paper, the spray development and its interaction with the piston geometry were investigated in a small-bore high-speed direct-injection optical diesel engine. The effects of injection angle, injection timing, injection pressure, and injection fuel quantity were studied. The entire liquid spray cycle was visualized by a background-corrected Mie-scattering technique using a high-speed digital video camera synchronized with a high-repetition-rate copper vapour laser. For some conditions, the initial injection velocity was estimated quantitatively. The results show that the injection angle

Abstract:
The method of supplying fuel for an electronic-controlled fuel injection system is calculating the required fuel amounts under various operating conditions of engine and controlling the opening and closing timing of fuel injection. After fuel injection, the effects of condensation and atomization of injected fuel as well as fuel mixing for combustion are strongly dominated by the opening timing and duration of intake valves. This can further affect the emission composition and performance for an engine. As the emission regulation is getting more stringent and the requirement for minimizing spe

Due to the problem of carbon dioxide (CO2) emissions, alternative fuels such as ammonia (NH3) have garnered a lot of attention lately. This is due to its carbon-free molecular structure, ease of transport, and high energy density.

To further investigate the burning characteristics of ammonia, this study is conducted for ammonia/gasoline co-combustion using a modified engine equipped with a sub-chamber.

The aim of this work is to investigate the effect of the multiple injections on the overall spray and the exhaust emissions characteristics in a common rail four cylinder diesel engine operated using diesel-ethanol blended fuels. In order to prevent the phase separation in blended fuels, biodiesel fuel that based on palm oil added to the blended fuels. The reduction problem of cetane number in blended fuels was supplemented by the addition of biodiesel fuel. The spray characteristics were analyzed through the spray images which obtained by the high speed camera. In addition, the combustion and

Abstract:
This paper describes an application of direct drive volume control (DDVC) to ship speed control. The DDVC fuel injection device consists of an AC servo motor, a fixed-displacement oil-hydraulic pump, and an oil-hydraulic cylinder. The cylinder piston pushes a fuel pump to pressurize fuel and an injection valve opens to inject fuel into a combustion chamber. Timing and the quantity of fuel injection can be controlled by the electric signal added to the AC servo motor. In this paper, the DDVC fuel injection device is applied to engine speed control of marine diesel engine and ship speed control.

Abstract:
Emissions regulations for off-highway engines are tightening towards those of on-highway engines. Present designs will not be able to meet these more stringent regulations because of their use of mechanical fuel injection timing control; more advanced timing control will be required. Ion sensing combined with variable fuel injection timing may help these engines meet the emissions requirements without the drastic price increase that usually accompanies a switch to advanced fuel injection technology. Ion sensing can detect the start of combustion and this signal can be used for closed loop cont

Abstract:
&lt;div class="section abstract"&gt;&lt;div class="htmlview paragraph"&gt;Split injection is widely used in conventional spark ignition engines to control mixture formation. To utilise split injection in a hydrogen direct injection engine, it is important to understand gas jet development and its variations with injection timing. This is because prolonged duration of gaseous fuel injection is required due to lower energy per volume than that of the liquid fuel, which causes complex jet-tumble interactions. The ambient air pressure and density during the gas injection also changes depending on

Abstract:
Precombustion chamber (PCC) ignition is a common method for extending the lean limit and reducing combustion variability in large bore natural gas engines. An important component that fails the most and requires regular replacement, besides the spark plug, is the checkvalve. In this program the use of an electronic valve for monitoring fuel to the PCC instead of the checkvalve is investigated. Other methods of improving PCC performance are also studied, such as nitrogen enrichment and PCC nozzle design. Additionally, emissions formation in the PCC is evaluated through the use of a separate pre

A retrofit lube oil injection system is designed with the capability of injecting oil through two lube ports on each cylinder at any time during the engine cycle. The system is installed and tested on a Cooper-Bessemer GMV4 engine. Variations in number of skip cycles, average lube rate, and injection timing are evaluated. Lube oil carry-over is quantified using a dilution tunnel and a standard particulate matter gravimetric measurement technique. Cylinder wall lubrication is quantified using a custom designed fixture that is inserted into the fuel valve port between data points when the engine

This study investigates the feasibility of injecting a premixed air and fuel charge into the precombustion chamber (PCC) of a Cooper-Bessemer GMV-4TF 2-stroke lean-burn natural gas engine. The primary ob-jectives are to enhance combustion stability, reduce emissions, and address the challenges associated with stratification within the PCC. Computational fluid dynamics (CFD) simulations were conducted to evaluate both ideal and practical premixed scenarios. The ideal premixed scenario aimed to achieve improved ho-mogeneity and faster flame propagation. Low-pressure premixed injections were test

Abstract:
Large-bore, natural gas-fueled engines are used for gas compression at over 1700 compression stations across the US, and methane emissions have presented a challenge to their optimization over the years. A significant root of this problem has been linked to the level of air-fuel mixing in the main combustion chamber of these engines as poor mixing results in low combustion efficiency. High-pressure fuel injection is believed to be a significant way to improve air-fuel mixing in natural gas engine combustion chambers. The purpose of this present study is to determine the sensitivity of in-cylin

Abstract:
There are over 7000 of large bore integral compressor engines distributed along the interstate and intrastate natural gas pipelines in the United States for gas compression. Methane emissions from large bore engines stem primarily from poor combustion efficiency. This study aims to improve the combustion efficiency of these engines, by reducing the amount of unburned methane that can escape through the crankcase vent and the exhaust gas emissions. Two broad approaches are taken to achieve this objective using experimental testing and computational studies: hydrogen blending and late cycle high

Abstract:
Emissions reduction through exhaust aftertreatment is becoming more common. It is likely to play an important role in meeting new emissions regulations in the future. Currently, the predominate aftertreatment technology for NOX reduction in lean burn natural gas engines appears to be selective catalytic reduction (SCR). In SCR, a reducing agent is injected into the exhaust upstream of a catalyst. Supplying the optimal quantity of reagent is critical to effective application of SCR. If too little reagent is supplied then the NOx reduction efficiency may be too low. If too much reagent is provid
