As a sensitive, flow-relevant component of the exhaust system on the combustion engine, the exhaust manifold is responsible for collecting the individual exhaust gases emitted by the cylinders and discharging them in a targeted manner.
This complex and flow-optimized component has a demanding task. Both the dimensioning and maximum fitting accuracy on the cylinder head, the high thermal stress caused by the peak temperatures on the turbocharger and the requirements for tightness against other exhaust components place the highest demands on the manifold.
HJS draws on its many years of development expertise in the thermodynamic design of exhaust components, as well as its knowledge of raw materials in steel and cast iron production.
A hairline crack in the exhaust manifold can have a faulty effect on the factory engine management system.
This manifold draws in “false air”, causing the lambda sensor to transmit incorrect measured values to the engine electronics. False air is a fault pattern that must be ruled out given the sensitive exhaust emission limits and applicable environmental legislation.
To simplify this process, HJS manifolds are supplied with all the necessary installation parts, such as gaskets, bolts and nuts.
