Pump Element Plunger 2418455196: Specifications, Applications, and Compatible Diesel Engines
The Pump Element Plunger 2418455196 is a high-precision fuel injection component designed for heavy-duty diesel engines. As a critical part of the injection pump assembly, it is responsible for generating high fuel pressure and ensuring accurate fuel delivery. Widely used in European truck engines and industrial applications, this plunger element plays a key role in efficient diesel engine maintenance and system reliability.
Product Overview
The 2418455196 plunger element (also written as 2 418 455 196 / 2455-196) is a Bosch-type pump element used in mechanical fuel injection systems. It operates within the injection pump barrel, compressing fuel and delivering it to injectors at precise timing intervals.
Engineered with high-precision machining and durable materials, this plunger ensures consistent fuel metering and stable engine operation under high-load conditions. It is commonly used in P-type (inline) injection pumps, which are widely applied in heavy-duty diesel engines.
