Highly Stress-Resistant Pistons for Improved Engine Efficiency
The demands on pistons in modern gasoline and diesel engines have significantly increased due to higher specific output levels. MAHLE's range of highly stress-resistant pistons plays a crucial role in reducing fuel consumption for both combustion types. These pistons are designed to withstand the thermal and mechanical loads, contributing to enhanced engine efficiency through weight reduction and minimized friction.
Innovative Solutions for Gasoline Pistons
The evolving requirements for gasoline engine pistons have pushed for innovative solutions to cope with heightened thermal loads. As performance demands rise, mean and peak pressures increase, along with greater inertia forces in high-speed concepts. MAHLE, with its years of experience, delivers cutting-edge solutions and continuously adapts its product range to meet future demands in the industry.
Forged Pistons: Strength and Performance
The transition from cast pistons to forged pistons marks a significant advancement widely adopted in motorsport and high-performance series engines. Forged pistons exhibit a finer microstructure and superior strength compared to their cast counterparts, making them ideal for withstanding extreme loads in motorsport and engines with high specific output. Their usage is increasingly seen in sporty series vehicles, offering benefits such as weight reduction through thinner walls.
Power Cell Unit: Enhanced Cylinder Components
Modern engines demand advanced cylinder components to operate efficiently at high temperatures and pressures while maintaining low emissions. MAHLE's power cell unit, comprising the piston with rings and pin, cylinder liner, and connecting rod with bearing shells, presents a comprehensive system designed for improved performance and ease of assembly. This integrated solution not only enhances engine efficiency but also offers commercial and logistical advantages to customers.
Innovative Diesel Pistons for Stringent Requirements
Today's passenger car diesel engines face demanding conditions, requiring pistons that can handle injection pressures up to 2,200 bar, mean pressures up to 31 bar, peak pressures up to 210 bar, and specific power output up to 100 kW per liter, all while reducing exhaust emissions. MAHLE has developed aluminum and steel diesel pistons to withstand the extreme temperatures and pressures, ensuring optimal performance and emissions control in modern diesel vehicles.
