マーレエンジンコンポーネンツジャパン Product Lineup

We offer "spheroidal graphite cast iron pistons" that can withstand high cylinder pressures of over 20 MPa. These pistons utilize our unique mold casting technology, achieving improved thermal and mechanical strength compared to aluminum pistons. Additionally, they are more cost-effective than forged steel pistons. 【Benefits】 ■ Compatible with high cylinder pressures over 20 MPa ■ Excellent thermal load performance ■ Heat insulation effect due to the low thermal conductivity of cast iron ■ Superior tribological properties (lubrication, friction resistance) due to the graphite contained in the metal structure compared to steel pistons ■ Improved wear resistance is also possible with gas soft nitriding treatment *For more details, please download the PDF or contact us.

We offer the 'MONOTHERM(R) piston,' designed as a one-piece structure for diesel engines, aimed at achieving lightweight and low-cost solutions for improved fuel efficiency. Depending on the application, you can choose between open and closed skirt structures. Please feel free to contact us if you have any requests. 【Benefits】 - Contributes to reduced friction at high temperatures due to a lower thermal expansion rate compared to aluminum pistons. - Potential for reduced cooling losses due to a lower thermal conductivity. - Reduced fluid friction due to a shorter skirt. - Lighter and more cost-effective than welded steel pistons. *For more details, please download the PDF or contact us.

Our company offers the "Kidney Cooling Cavity TopWeld® Piston," which optimizes cooling efficiency and reduces mechanical losses for next-generation engines. The specially designed kidney shape is formed through machining. The up-and-down motion of the piston induces and accelerates the flow of cooling oil, achieving high cooling efficiency. 【Benefits】 - The temperature at the combustion chamber inlet and the tip of the cooling cavity can be reduced by up to 20°C compared to standard piston types. - The reduction in temperature contributes to the suppression of oil degradation. - By reducing the required amount of oil for piston cooling, there is potential for decreasing the discharge volume of the oil pump and mechanical losses. *For more details, please download the PDF or contact us.
