How start-stop can cause damage to engine and surrounding components

Pulleys and engine mounts have to withstand ten times more vibrations over a lifetime

Corteco has highlighted the possible “detrimental effect” start-stop technology could have on what it describes as “inferior engine and vibration control components”.

It warns that start-stop increases the strain on components by increasing the vibrations transmitted throughout the auxiliary drive via the crankshaft pulley and engine mount.

Typically on average an ordinary pulley and engine mount will have to withstand up to 50,000 to 70,000 starts over the lifetime of the vehicle.

However, under the start-stop system a pulley and engine mount will have to endure 500,000 to 700,000 starts increasing the vibrations transmitted by ten times.

Developing engine mounts and pulleys that can withstand as many starts without breaking or failing, poses enormous challenges.

Extensive research, development and testing carried out by Freudenberg makes it possible to deliver these solutions.

A Corteco spokesperson said: “Counterfeit or inferior parts are exposed to none of these stages and therefore cannot match OE requirements.

“Installing a counterfeit or ‘white boxed good’ into a vehicle with start-stop capabilities can risk other components in the auxiliary drive.

“As vibration control parts are used to absorb excess vibrations from leaking and damaging surrounding components it is imperative to install quality products that can effectively achieve this.

“Vibrations often arise as a result of aging components or poor quality vibration dampers.

“These vibrations don’t just affect driving comfort.

“Unwanted vibrations can spread throughout the vehicle and cause damage to the engine and other components.

“Without quality parts being used the vehicle will be returned to the garage for several repairs due to premature failure of surrounding components.”

Corteco stocks over 1,410 components for vibration control that have been designed especially for start-stop systems and the pressures it puts on the other components found within and around the engine.

    More and more new vehicles are leaving the factory with start-stop technology installed. The technology is increasingly being used to tackle emissions

    Another dumb idea, stop start battery three times the price, then
    Often find they are 3 hernias in weight compared to standard 1 hernia in weight.

    Then your double solenoid starter, just to save half a second cranking time.
    To add to confusion on push button non start job

    Bad idea, whoever designed the technology- go clean 300 toilets.
