The Effect of Combustion Chamber Volume and Engine Rotation on Temperature and Compression Pressure of Single Cylinder Diesel Engine

Abstract

The effect of combustion chamber volume and engine rotation on the temperature and
compression pressure of this single-cylinder diesel engine aims to convert the use of diesel
fuel in diesel engines into gasoline fuel by utilizing high compression without using the
help of spark plugs during ignition. The main focus of the study is to understand the effect
of variations in combustion chamber volume and engine rotation on temperature and
compression pressure in order to find optimal operating conditions. The General 170fd
single-cylinder diesel engine was used as the object of research. The testing tools used
include the TC-08 Thermocouple sensor module, the thermocouple sensor, and the
pressure gauge to measure the temperature and compression pressure. The research was
carried out using various gasket thicknesses, namely 0.6mm, 0.8mm, 1.4mm, 1.6mm, and
1.8mm to vary the volume of the combustion chamber. The data collected was analyzed
to determine the relationship between changes in the volume of the combustion chamber
and engine rotation to the temperature and compression pressure. The results of the study
are expected to provide insight into the ideal conditions for gasoline ignition in diesel
engines without the use of spark plugs, as well as contribute to efforts to optimize the use
of alternative fuels. The results of the experiment showed that variations in the volume of
the combustion chamber and engine rotation had a significant impact on the temperature
and compression pressure. The determination of the appropriate temperature and
compression pressure is expected to improve the efficiency and performance of diesel
engines when using gasoline fuel, thereby reducing operational costs and increasing the
flexibility of engine use in various applications. This research makes an important
contribution to the understanding of diesel engine modifications for gasoline fuel use,
which can be applied without testing exhaust emissions, with a focus on ideal temperature
and compression pressure.
