A lot of research has been done on internal combustion engine to reduce fuel consumption and emission. One field is being researched today is to recuperate from kinetic energy to electric energy as a vehicle deceleration status. More energy recuperation can be reduced fuel consumption. To recuperate the more electric energy, this study was applied to the high power alternator and AGM battery device and optimized voltage control. This kind of system is new generation alternator management system. The result of fuel economy test for this system showed an about 0.8~4% improvement effect.

A lot of research has been done on power train cooling system to reduce fuel consumption and emission. Known engine cooling techniques are an electric water pump with an electric thermostat, an electric water valve, a clutch water pump and so on. The common approaches to enhance fuel economy among these techniques are fast warm up and control coolant temperature high. This paper discuss the amount of fuel economy enhancements on a engine with fast warm up technique, control coolant temperature high, control automatic transmission fluid temperature high.

Fuel efficiency is the one of the major issues in the aspect of energy. environment. As customers desire more comfortable vehicles, increases of accessory traction forces are necessary. Air conditioning system (ACS) consumes the biggest traction forces among accessories, especially during summer. This means ACS is the primary object deteriorating fuel economy among accessories. Since direct measurement of traction force and fuel consumption in practical vehicle is difficulties, comparison analyses are taken between vehicle with ACS working and without ACS. For this comparison. real time measurements are carried out to know ACS traction force and fuel consumption. As a result of the comparison, a vehicle without ACS operation was 15.92% superior to a vehicle with ACS operating. It could be used as a fundamental material for improvement ACS for better fuel efficiency.

Fuel economy is one of the major issues in regard to energy and environment. Customers demand the improvement of fuel efficiency and drive ability. because of this cause, I make an experiment and simulation on DSP engine which can improve fuel efficiency and drive ability. Dual spark plug(DSP) system engine can realized the customers desire. As a result of an engine test, The DSP system engine shows fast combustion and high thermal efficiency. Indicated thermal efficiency of DSP system engine compared with SSP system engine is improved up to 2~4%. Also, DSP system engine shows the improvement of 2~5% fuel consumption rate at the main driving zone. COV indicated drive ability is about 1%. According to a result of simulation, DSP engine appears to be increasing 4.7% fuel efficiency.

Recently, the main ingredient of the greenhouse gas, CO2 and the fuel consumption rate is raised on an international problem, so the motor manufacturers are concentrated to develop the techniques about it. The techniques and fuel efficiency improvement are developed for the direct method such as the improvement of engine and the advice device of improving the driving habit. In this study the fuel consumption about the various routes that customers grasp the traffic to the destination before the driving was forecasted and the algorithm for the best route was developed. The energy efficiency map and the fuel consumption production in this algorithm are the very core. The prospect accuracy of the algorithm is confirmed by the driving test and it is confirmed that the driving route information system realizing this algorithm improves the fuel efficiency.

The purpose of this study is development of Automatic Transmission Fluid warmer for the fuel economy. In this paper, experiments conducted to develop ATF Warmer & Cooler with Same Cooling Performance of Conventional Water Cooled Oil Cooler. Stacked plate heat exchanger applied in ATF Warmer to investigate the heat transfer characteristic and relationship between operating parameter and effect of the fuel economy. The results show that the friction of Automatic transmission fluid decrease in the fast warm up conditions and this effects make 0.7~1.2% of fuel economy improvement.
