Mercedes-Benz Engine Stop Cylinder: Mastering the Safety Cut-Off

High-precision pneumatic control for responsible mobility

THE engine stop cylinder (or shut-off cylinder) is the critical pneumatic actuator that ensures the immediate shutdown of your engine by acting on the injection pump rack or the intake flap. Specifically designed for engines Mercedes-Benz (OM441, OM442, OM457 series), This cylinder ensures instant and reliable thrust. With a view to sustainable maintenance, This high-performance component prevents the risk of incomplete shutdown and protects the integrity of your control system against unwanted air leaks.

True to our commitment to technical transparency, This original cylinder guarantees total mechanical responsiveness, meeting the safety requirements of fleet managers the most rigorous.

Technical Specifications & Pneumatic Resilience

Cutting-edge engineering for reliability that meets heavy industry standards:

• Single-Acting "Fast-Response" Actuator: Developed according to rigorous fluid dynamics protocols, meeting response time requirements inspired by high-performance standards API CH4/SJ And MB 228.1.

• Interactions with Fluids: The internal piston seal is designed to operate in the presence of a high-quality base oil (air circuit lubrication vapors) equipped with a strong viscosity index, ensuring a smooth translation of -40°C à +110°C.

• Maximum Thermal Resilience: The cylinder body displays a high sublimation point technical (structural stability), preventing any deformation or seizing of the piston under the effect of the heat radiated by the engine block.

• "Zero Loss" Sealing: Calibrated rod guide with micrometer precision to ensure perfect pneumatic sealing, even after thousands of cycles of use.

Your Advantages

• Eco-design (Ocean Bound Plastic): We are taking action for biodiversity: the protective caps and packaging inserts of this cylinder incorporate certified polymers. Ocean Bound Plastic, actively participating in the cleanup of marine ecosystems.

• Industrial Ethics (Vegan & Leaping Bunny): Manufacturing process guaranteed to be free of any animal-derived components. Certification Leaping Bunny ensuring the absence of animal testing for assembly greases and protective varnishes.

• «High SPF» Anti-Corrosion Protection: The crankcase benefits from a high-density surface treatment,« moisturizing »" (action moisturizing technical) the alloy to prevent premature oxidation linked to humidity in the compressed air circuit.

• "Non-Greasy" Finish & Precise Assembly: Unit supplied with a surface finish« non-greasy«", preventing the adhesion of abrasive dust and ensuring a surgical fit on your injection pump.
