“…In the paper [6], the effect of the pilot fuel mass of a dual-fuel engine working on gas-diesel mode on the combustion process and emissions was experimentally defined. It was investigated that an increase in the pilot fuel mass leads to a decrease in combustion delay and an increase in the amount of NO x emissions.…”

Modern research in the area of internal combustion engines is focused on researching and investigating the technologies that will improve fuel efficiency and decrease emissions. Application of dual-fuel engines is considered as a potential solution to these problems. In the dual-fuel engine, a natural gas-air mixture is ignited by a small amount of the diesel fuel directly injected into a combustion chamber. Pilot fuel injection parameters can strongly effect the combustion process. The aim of this paper is to investigate the effect of such fuel-supply parameters as pilot fuel mass, pilot fuel injection pressure, pilot fuel injection timing and excess air ratio on the combustion process. Investigation is based on the data obtained during bench tests conducted with the use of measurement equipment. The dependences of engine characteristics from the fuel supply parameters under review were obtained based on the results of the experimental study. Optimal values for every investigated fuel-supply parameter were chosen based on the obtained results. Over the course of the investigation, the coefficient for heat release rate according to the Vibe equation was calculated for each operating point.

Abstract. A proper design of the compression ignition engine fuel system requires various fuel injection methods analysis. Direct and indirect CNG injection process simulation research was conducted. The results allow a mixture homogeneity analysis and its impact on combustion process and heat transfer. For an indirect injection the injector is placed in intake channel and the injection is performed during an intake stroke. For a direct injection the specially designed injector is installed in the glow plug position. The analysed case is set for 20% energetic ratio of diesel fuel and 80% of methane fuel. In order to perform the calculations a special combustion model has been implemented that allows duel-fuel combustion in a compression ignition engine.

“…There are many types of gas fuel, such as natural gas and petroleum gas. In the storage and distribution of natural gas consists of two forms, namely, compressed natural gas (CNG) and liquefied natural gas (LNG) [4]- [6]. Compressed natural gas (CNG) is an alternative fuel besides gasoline or diesel [7].…”

The modification of diesel engine into the dual-fuel engine or specifically gas-oil fuel engine has been done to solve the problem of the depletion fossil fuel oil reserves in the world. Fossil fuel oil reserves are projected to be exhausted in the next 50 years or less by prediction. The working system of the gas-oil fuel engine was injecting (gas fuel) to combustion chamber along with the air during the suction step in the intake manifold and burned with the diesel as the lighter. The gas fuel was used here is CNG (Compressed Natural Gas). But the performance of the engine when using the addition of gas fuel has decreased. The modification, like the addition of fixed fin in the air intake valve, is done to increase the swirl ratio. So, that turbulent flow of air comes in along with the gas fuel to be better. As a result, the combustion process in the combustion chamber got better. By applying a fixed fin addition into the air intake valve gas-oil fuel engine, it can increase engine performance better. The power generated by the engine with fin adding increases at maximum load. While torque of engine with fin adding increased in maximum load condition. For specific energy consumption (SEC) has been decreased impact of the fin, adding on the air intake valve.
