The Impact

The article presents an overview of methods for the production of bioethanol and the possibility of its use to power internalcombustion engines. The effects of supplying spark-ignition engine with bioethanol having various degrees of hydration were examined experimentally on the engine dynamometer. The measurement results were referred to the anhydrous bioethanol, which is used widely as petrol biocomponent and compared in terms of the course of the pressure in the combustion chamber of the engine as well as engine performance parameters – torque and power. It was found that with the decrease in alcohol concentration, the performance of the sparkignition engine deteriorated. The reduction of in-cylinder pressure was proportional to the increase in the water content in the fuel. No significant changes in the general shape of in-cylinder pressure curves were observed. Engine torque and power decreased with an increase in the water content in the fuel, especially at high engine speed. It has been stated that supplying the engine with bioethanol containing up to 6% (v/v) of water does not result in significant losses in engine performance.

Oil Blend

This paper presents the results of an investigation on the effect of 2T oil blend on the performance of Spark Ignition (SI) engine. Three different types of 2T-oils; mineral oil, semi-synthetic oil and fully synthetic oil were tested according to blend ratio before the mixing process with fuel in the carburetor. In the experiment, a two-stroke single-cylinder engine was coupled to a 20 kW generator dynamometer to measure engine performance parameters; engine torque, engine power (B.P), brake thermal efficiency (BTE), brake specific fuel consumption (BSFC) and brake mean effective pressure (BMEP) at various engine speeds with maximum engine load. The results show correlation between engine performances and 2T-oil blended as a function of type of 2T-oils used.

Hydrogen Enrichment

Hydrogen enrichment in internal combustion engines has been a topic of research interest to improve engine efficiencies and reduce carbon emissions. Hydrogen enrichment has garnered more interest than the pure hydrogen powered engines due to less complexity involved with the modifications of the engine and fuel system as well as the infrastructure required for it. Similarly, accurate chemical kinetics has proved to provide accurate results in terms of engine performance parameters, such as, in-cylinder pressure. The present study is an extension of study performed earlier with hydrogen enrichment in gasoline direct injection engine while using C8 H17 as a surrogate fuel for gasoline and assumes that an on-board electrolysis system installed on the vehicle produces hydrogen for the enrichment purposes. A mesh independent study is performed using 90% iso-octane (iC8 H18) and 10% n-heptane (nC7 H16) blend as a gasoline surrogate with hydrogen enrichment of 0%, 1%, 2% and 3% at equivalence ratios of 0.98 and 1.3, in a premixed spark ignition engine. Numerical simulations are performed to calculate and compare the thermal and combustion efficiencies of the engine using hydrogen-enriched fuel versus iso-octane and n-heptane blend. The study also predicts and measures the engine performance parameter of in-cylinder pressure, while comparing the iso-octane and n-heptane blend against the blend enriched with hydrogen. Based on the results obtained from smaller hydrogen enrichment concentrations, the study increases the hydrogen-enrichment of the fuel to 5%, 10% and 15% to analyse the effects of enrichment on the thermal and combustion efficiencies, as well as the in-cylinder pressure.

Three different types of material; paper, cotton and foam were tested as filtering element in the air filter before the mixing process with fuel in the carburettor. In the experiment, a four-stroke single-cylinder engine was coupled to a 20 kW generator dynamometer to measure engine performance parameters; engine torque, engine power (B.P), brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) at various engine speeds with maximum engine load. The results show correlation between engine performance and the qualities of filtered air as a function of type of air filter element/material used.

High Engine Speed

The depletion of fossil fuel resource is creating demand for new renewable energy resources. An experimental study was conducted in order to determine effects of various fuel blends including small amount of ethanol, naphthalene and palm oil in petrol on a single cylinder spark ignition engine. Engine performance and fuel consumption were investigated using an engine dynamometer with various loads and engine speed. Engine performance was obtained by recording the engine torque during low, medium and high engine speed from 1200 rpm - 4700 rpm. Fuel consumption of the blends was determined by the brake specific fuel consumption. Palm oil showed about 50% reduction in engine torque for the blends of 3 % and 5 %, while naphthalene showed about 11% reduction for the engine torque when the engine speed is more than 4000 rpm. Ethanol showed a slight improvement of about 1% in engine torque. 20% of ethanol blending fuel gave out the best result in terms of torque. Besides, 20% of ethanol blend found to be decreased in fuel consumption for about 9% when running at 2500 rpm in comparison with 100% petrol.

The Impact

The paper is focused on the impact of clogged air filter on a change of speed characteristics of spark-ignition engine 1.4 MPI, 16V, 74 kW. The clogged air filter can cause deterioration in engine charging. Less air means the possibility of burning smaller amount of fuel, and thus less energy brought to the engine. This should cause a change in the size of engine torque and its power.

Considering the enhancement device for air intake systems have been widely available in the market for automotive engines, in this paper, the effect of Supercharged Air Filter (SAF) system on a Spark Ignition (SI) engine were experimentally investigated. Three different types of air filter; standard, conical shape air filter and SAF were tested on a four-stroke single-cylinder engine. The engine was coupled to a 20kW generator dynamometer to measure engine performance parameters; engine torque, engine power (B.P), brake thermal efficiency (BTE), brake specific fuel consumption (BSFC) and brake mean effective pressure (BMEP) at various engine speeds with maximum engine load. The results show that the forced induction system can affect the engine performance but it will make the engines fuel consumption higher than standard system.
