The "bond" between the engine and the gasket
The interior of an automobile engine's cylinder is subject to extreme conditions, with the piston running up to 6,000 times each minute, as well as the vibration, shock this generates, and the high heat and pressure resulting from combustion in the cylinder. Under such conditions, gasket only about one millimeter thick are required to exhibit proper mechanical strength, heat resistance, durability, and ability to maintain their resilience. It is no exaggeration to say gaskets are critical parts that have a tremendous effect on an engine performance.
Taking the "Concept-In" Approach
The relationship between engines and gaskets is so close that it is said one can't know how the gasket should be formed without knowing the engine it is to be used with. This means that the development of a gasket starts with the development of that engine. Development at Nippon Gasket is based on the "Concept-in" approach, whereby we repeatedly meet with the manufacturer for detailed discussions, develop gaskets optimally suited for that engine, and following rigorous evaluation and testing to ensure we can follow through on our pledges for safety and reliability, we then offer the product to the manufacturer.
