Thermal Performance Analysis for a Remodified Diesel Engine to Improve Fuel Efficiency

Abstract

Heavy trucks, buses, lorries, and other vehicles require over Rs. 4 lakh crores of diesel each year, which is imported at a cost of approximately Rs. 5 lakh crores annually. These cars' engines use water cooling, which keeps the internal engine components below 100°C.For the following reasons, the material temperature is kept below 100°C. The water in the radiator will boil if the cylinder temperature exceeds 100°C. The liquid lubricant burns and becomes sticky over 140°C, which causes the engine to seize. As a result, the need for a liquid lubricant, the need to cool the radiator and engine cylinders, and the loss of 35 to 40% of the heat equivalent of the diesel can all be avoided. In order to accomplish this, a second stainless steel cylinder is added above the existing conventional engine cylinder. A stainless steel piston then glides inside the stainless steel cylinder, maintaining a very small clearance and requiring no lubrication. A stainless steel piston rod guided by bearings connects the stainless steel piston to the traditional engine piston, and the two pistons reciprocate as a single unit. The traditional cylinder and piston are now just utilized to guide the piston assembly and bearings; the firing has been relocated to a stainless steel cylinder. As a result, the engine's heat flow will be reduced, increasing efficiency. As a result, the radiator is turned off because the traditional cylinder isn't burning, saving 35 to 40 percent of the gasoline that would have been lost to heat dissipation through the radiator. As a result, improving the efficiency of all large trucks could save up to 40 to 50% of the diesel used by large trucks, as well as 1.5 to 2 lakh crores of rupees per year, making this research of national significance

Key findings

• ▸The current diesel engine design wastes 35-40% of heat energy due to water cooling and liquid lubricant.
• ▸A stainless steel cylinder and piston design can maintain a small clearance and eliminate the need for lubrication.
• ▸The proposed design can potentially reduce fuel consumption and cost for heavy vehicles.
