Small Engine Cooling and the Electric Water Pump

The heat produced in turbocharger has the potential to destroy the bearing system and the oil piston ring. For the past years, the researchers have focused on heat transfer of micro turbocharger. The lack of research on the cooling system of the turbocharger has motivated the author to publish this paper. In this paper, the electrical water pump with air blower is used to reduce the heat effect. The impact of adding electric water pump o heat distribution on turbocharger has been discovered by conducting experimental research. The experimental research was conducted on one cylinder, two-stroke with Lifan engine 160 cc equipped with the turbocharger. The temperatures of the turbine, bearing housing, coolant inlet and outlet are measured and analyzed in this turbocharged engine test rig.

Radiators are heat exchangers used to transfer thermal energy from one medium to another for the purpose of cooling and heating. The majority of radiators are designed to service in four wheeler and heavy duty vehicles. The radiator is always a origin of heat to its environment, although this may be for either the function for cooling the fluid or of heating this environment, or coolant supplied to it, as for engine cooling. In existing plain fins type radiator are commonly used, which are usually set up in a cross flow arrangement made up of aluminum and copper alloy. Powerful fan and water pump is accompanied in this to greatly improve heat dissipation rate. The addition of fins is one of the way to improve and increase the rate of radiator cooling. This method follow the principle of increasing contact surface. Contact surface can also be increased by varying fin geometrical structure. In this project simple modification has been carried out in the existing fin geometry with a view to improve its heat dissipated rate. Also comparison of conventional coolant with Nanofluids has been carried out by using PTC Creo 3.0 and analysis is carried out by using Ansys v16. The result are compared and optimum fin design is concluded.

Cavitation Performance

To analyze the internal flow of the engine cooling water pump (ECWP) under thermodynamic effect, Zwart cavitation model based on the Rayleigh-Plesset equation is corrected, and NACA0015 hydrofoil was selected to verify the corrected model. The cavitation performances of ECWP with different temperatures were numerically simulated based on a corrected cavitation model. Research results show that simulation values of pressure distribution coefficient in hydrofoil surface at 70 °C are in closest agreement with experimental values when the evaporation and condensation coefficients are 10 and 0.002, respectively. With the decrease of absolute pressure in pump inlet, bubbles firstly occurred at the blade inlet side near the suction surface and then gradually extended to the pressure surface, finally clogged the impeller passage. Compared to the inlet section, the cavitation degree is much more serious close to the trailing edge. With the temperature increases, the cavitation in ECWP occurs in advance and rapidly, and the temperature plays an important role in promoting cavitation process in ECWP. Based on the unsteady simulation of ECWP, the influence of cavitation on the performance characteristics is studied. The results provide a theoretical reference for the prediction and optimization of the cavitation performance in ECWP.

Simulator Test

A cooling system employed in an automobile is to maintain the desired coolant temperature thus ensuring for optimum engine operation. Forced convection obtained by means of a water pump will enhance the cooling effect. Thus it is necessary to understand the system’s pump operation and be able to provide for the ultimate cooling of the engine. The objective of this laboratory investigation is to study the water pump characteristics of an engine cooling system. The crucial water pump parameters are the head, power, and its efficiency. In order to investigate the water pump characteristic a dedicated automotive cooling simulator test rig was designed and developed. All of the data obtained are important towards designing for a more efficient water pump such as electric pump that is independent of the power from the engine. In addition to this fact, the simulator test rig can also be used to investigate for any other parameters and products such as radiator performance and electric pump before installation in the actual engine cooling system. From the experiment conducted to simulate for the performance of a cooling system of a Proton Wira (4G15), the maximum power equals to 37 W which indicates the efficiency of the pump is relatively too low as compared to the typical power consume by the pump from the engine which are about 1 to 2 kW. Whereas the maximum power and efficiency obtained from the simulator test rig simulator is equals to 42 W and 15% respectively.
