Hi everyone

I've just bought a 2019 Focus Mk4 1.0 Ecoboost. 56000 miles on the clock. 

I am new to these 3 cylinder ford engines and I found it quite noisy. Today, I opened the bonnet and noticed that the engine was vibrating, almost shaking. I googled it and it seems it is normal to have some level of vibration for 3 cylinder engines but it seems it is more than normal in my case.  I don't have any problem when driving. The engine is smooth, accelerates well, I get 40 mpg in city traffic. 

Looking forward to hearing from you. Any advice is appreciated.

That looks fairly typical to me. The 3 cylinder engines do shake/vibrate at low RPM. Is your car manual or automatic?

Thanks for the reply.  It is a manual gearbox focus

Then you can expect a little more shake at idle than the automatic which has a balancer shaft fitted inside the engine. With the manual the clutch/flywheel assembly helps smooth the shake.

Looks ok to me. Fairly similar amount of "shake" to my current 1.5. My previous 1.0 Ecoboost rocked around more and looked like it was making a bid for freedom, but always felt very smooth from inside the car.

On noise, opinions/experiences seem to differ but to me the revised (chain cam) engines (as in the Focus Mk 4) never seem as smooth/quiet as the wet belt versions. 

3 cylinder engines do tend to take a little getting used to when you're more accustomed to 4 or more, but both our cars have been 3 cyl for over 6 years, so I find a 4 cyl feels a bit odd when I drive one now!😀

Thanks Eric, 

 

It is really helpful.  I think you're right,  I need time to adapt myself to 3 cylinder engines

looks like it's trying to escape

Lol, you can't do this with a 1.0 Ecoboost, for sure:

 

That shaking does look normal. You mentioned you've just bought the car, so take a look at the engine mounts. They have a rubber part which absorbs most of the shaking so it doesn't "spread" to the body. At some point those need changing so take a look now to see if they seem in good condition. As you said, there should be no shaking during driving/accelerating/braking.

The traditional way of reducing shaking forces in small-displacement engines is to install a counter-rotating balance shaft inside the motor that cancels out most vibrations. But the problem with a balance shaft, explains Andy Delicata, Ford of Europe manager of Powertrain Noise, Vibration and Harshness, is that it is heavy, expensive, and it reduces fuel economy.

The 1.0-litre’s NVH engineering team, led by Delicata at Ford Technical Centres in Dunton and Dagenham, England, attacked the problem by focusing on two areas – the engine’s front pulley and rear flywheel, and the mounting system that connects the powertrain with the car’s body.
