“…This phenomenon adversely affects fuel economy, emissions, the overall engine efficiency and ultimately its service life. The measured results correspond with the cylinder pressure variation published by Binjuwair and Alkudsi (2016). A greater ignition timing angle results in a higher increase in pressure in the cylinder and pressure peaks closer to the top dead centre in the expansion stroke.…”

“…This assumption will be confirmed or refuted by the curves of the cylinder pressure variation. Binjuwair and Alkudsi (2016) published similar experimental measurements for a four-stroke single-cylinder engine with the same compression ratio, engine speed and at full throttle. The engine geometry parameters per cylinder (bore, stroke, displacement) and ignition timings are almost identical.…”

“…This is also confirmed by the fact that changing the ignition timing is reflected in the emissions -the amount of unburned hydrocarbons CxHy, nitrogen oxides NOx and carbon oxides COx. (Binjuwair and Alkudsi, 2016) This article evaluates the effect of the ignition timing on the basic parameters of a four-cylinder engine that runs on unleaded gasoline. The main assessed parameters include the output parameters of the engine, cylinder pressure variation, heat generation and burn rate.…”

This article deals with the effect of the ignition timing on the output parameters of a spark-ignition engine. The main assessed parameters include the output parameters of the engine (engine power and torque), cylinder pressure variation, heat generation and burn rate. However, the article also discusses the effect of the ignition timing on the temperature of exhaust gases, the indicated mean effective pressure, the combustion duration, combustion stability, etc. All measurements were performed in an engine test room in the Department of Technology and Automobile Transport at Mendel University in Brno, on a four-cylinder AUDI engine with a maximum power of 110 kW, as indicated by the manufacturer. To control and change the ignition timing of the engine, a fully programmable Magneti Marelli control unit was used. The experimental measurements were performed on 8 different ignition timings, from 18 °CA to 32 °CA BTDC at wide throttle open and a constant engine speed (2500 rpm), with a stoichiometric mixture fraction. The measurement results showed that as the ignition timing increases, the engine power and torque also increase. The increase in these parameters is a reflection of higher pressure in the cylinder, the maximum value of which is achieved at a higher ignition timing near top dead centre in thepower stroke. In these conditions we can expect higher engine efficiency. It was also found that the combustion is more stable with a higher value of ignition timing. No significant difference was found in the combustion duration.

“…Another study [26] which was also similar, researched on the effects of RON and fuel system on SI engine performance and emissions by using Saudi Arabian RON91 and RON95 fuel with port injection and direct injection system. They also worked on the effects of varying spark timing on the performance and emission characteristics using the same mentioned fuel RONs [27]. Other studies that tried to examine between two fuel grades (RON90 & RON95) was performed Ali Alahmer and Wail Aladayleh [28], where they found using octane grades higher than requirement will decreased the engine performance but will have lower NOx and CO emission concentration for the higher RON.…”

Engine performance testing using variable RON95 fuel brands available in Malaysia

Abstract. There are various gasoline fuel producers available in Malaysia. The effects of fuel variations from different manufacturers on vehicle performance have always been a debate among users and currently the facts still remains inconclusive. Hence, this study focuses on analyzing various RON95 fuel brands available in the Malaysian market and finding the differences towards engine performance. In terms of engine output, the important data of power (hp) and torque (Nm) will be gathered by using an engine dynamometer. Another data that would also be taken into account is the knocking where the relative knock index can be measured in percentage using the knock sensor accelerometer. Results have shown that the performance of different fuel brands tested are indeed different albeit by only a small margin even though all fuels are categorized with the same octane rating. The power and torque results also imply that both are influenced by the amount of vibration generated due to engine knocking. Based from the overall outcome, consumers would not need to only focus on a certain type of gasoline brand as all differentiates the engine performance marginally.

Developing more energy-efficient and environmentally friendly transportation technologies, that can enable to use significantly less petroleum and to reduce regulated emissions while meeting or exceeding drivers' performance expectations, has always been one of the main challenges in automotive technology. Therefore, based on an experimental dataset, metamodels were generated using design of computer experiments and central composite design technique in order to accurately predict carbon monoxide (CO), oxides of nitrogen (NO x ), hydrocarbon (HC) and carbon dioxide (CO 2 ) emissions, mean effective pressure and exergy destruction due to heat transfer and combustion process. Combustion metamodels was evaluated varying air-fuel ratio, ignition timing [( • CAD) Crank Angle Degrees], compression ratio, and combustion duration ( • ) on the performance of a Spark Ignition (SI) engine at constant speed of 750 rpm. Because SI gasoline engines always encounter the decreased thermal efficiency and increased toxic emissions at idle (Jurgen in Automotive electronics handbook, McGraw-Hill, New York, 1995). The Akaike information criterion was applied to automatically select the best metamodel for each case.
