Since the invention of the internal combustion engines, Automotive engineers are finding ways to increase engine power that one way is supercharger. It was developed to assist internal combustion engines in improving performance and power of the engine, But these plans have deficiency as Intercoolers and Turbo Lag and etc.but this new designed system to cause launching a diaphragm pump by use of the linear motion in suspension system then compressed air is stored in tank and by using the directional control valve 3/4 with the states of off-sport 1and sport 2 we can increase engine power. The results of torque ,BSFC(Brake specific fuel consumption) and indicator diagrams(p-v) show increased horsepower And the advantages of this plan are that we don’t have turbo lag for the sudden acceleration and also due to the air tank for supplying mass flow-rate the vehicle can cross the shallow water and submerged.

Along with the development of internal combustion engines, camshafts have also been developed to optimize engine performance. In all types of internal combustion engines, the crankshaft is connected to the camshaft via a toothed belt, chain or pinion. When the crankshaft turns, the camshaft spins and opens and closes the intake and exhaust valve respectively. However, in this non-camshaft engine technology, each intake and exhaust valve will be integrated with an electronically controlled hydraulic pump unit. This system provides a unique ability to independently control intake and exhaust valves. For any engine load, load and discharge times can be programmed independently. The decision system is based on driving conditions, used to maximize performance or minimize fuel consumption and emissions. This allows a greater degree of control over the engine which in turn provides significant performance benefits. This article presents reviews of camshaftless technology developed by VALEO. It is a system that uses solenoid valves to open and close the valve. The solenoid valve will be mounted right on top of the valve inside the engine. The author can see that the technology using this electronic control valve will help reduce the fuel consumption of the engine.

The efficiency of cavitation treatment of water-gasoline fuel mixture for power supply of automobile internal combustion engines has been experimentally investigated. It is established that cavitation treatment of this fuel mixture allows to increase the water content in it up to 15–17%, reducing the engine power by only 6–7%. This allows up to 10–15% to increase the cost of gasoline when running engines in city traffic jams and on flat and sloping sections of highways. The description of the automobile electromagnetic vibrating cavitator developed for cavitation processing of water-gasoline fuel which not only provides fuel, economy, but also increases degree of completeness of combustion of water-gasoline fuel mix is resulted. As a result, the ecology of the environment is improving.

Alternative fuel source such as ethanol possess great potential to replace conventional fuels such as petrol and diesel. There has been a great increase in the usage of such fuels in the developing world, of late, with many countries having already mandated the usage of ethanol blended petrol. In developing countries, two stroke internal combustion engines continue to be used for powering agricultural implements and auto rickshaws. This paper presents the experimental investigations carried out on the usage of petrol blended with different proportions of ethanol by volume (5%, and 10%) as a fuel for an unmodified and used 100cc two stroke SI engine. The objectives of the experimental investigations are to determine whether ethanol blended petrol can be used as a suitable fuel for the commonly used two stroke internal combustion engine without any modifications. Tests were carried out on the engine, with petrol as the fuel initially and then with ethanol blended petrol with increasing proportion of ethanol. The total fuel consumption rate seemed to increase upon addition of ethanol. However, the brake specific fuel consumption remained fairly constant. The fact that brake specific fuel consumption varies only marginally indicate that ethanol can be used as a substitute for petrol, as a fuel.

Internal combustion engines are the main power source for  automobile vehicles.  As current  emission regulations becomes more stringent, more fuel efficient and less polluting engines are becoming the focus of car manufacturers. This paper presents the study of improving the performance of K3-VE I4 internal combustion engine that is used in the Perodua Myvi for the Perodua Eco-Challenge 2013. The strategy was  to use an EGR system to reduce Brake Specific Fuel Consumption (BSFC) while maintaining or increasing the engine power. The effects of different location of EGR on the engine performance were tested on a chassis dynamometer. The sensitivity of the engine performance and gas emission were studied since EGR implementation plays a  major role in influencing NOx emission. The performance parameter such as engine power and BSFC were then analysed. The result shows that a significant increase of power can be achieved and a reduction of around 56% was obtained on the BSFC. While the best NOx reduction was around 93%. These improvements are obtained at low RPM that corresponds to Perodua Eco-Challenge’s objective.

Background: Biofuels are one of the promising alternative fuel sources for automobiles. The use of biofuels in combustion engines of automobiles showed many advantages and disadvantages. In this study, the advantages and disadvantages of using biofuels in internal combustion engines are reviewed and summarized based on early studies. Biofuels can offer favorable well-towheel CO2 balance in our environment and improve engine power and efficiency. Oxygen contents in biofuels also provide advantages for the fuel combustion. However, biofuels, also showed some disadvantages, like corrosiveness to engine systems and low heating values of biofuels. Boiling temperature, absorption with water, vapor toxicity, and autoignition of biofuels showed advantages for some types and drawbacks for others.
