I've always found it a lot easier to avoid stalling in a derv than a petrol. Deva Link 26, posts months. FoolOnTheHill 1, posts months. They don't stall as easily as petrols, but once they stall, unlike a petrol there's no chance to recover it. HellDiver 5, posts months. Modern diesels don't have the same low end torque as the old lumps of years ago. Before rpm and the turbo they're pretty gutless. Dual mass flywheels don't help either. StevenB posts months. Transit diesels are very easy to stall they don't like pulling away with min.
You need to keep the revs between rpm and rpm the diesel narrow power band to pull off. Munter 30, posts months.
It seems to be more of a problem with new diesel engines. There was a thread recenetly where it seems that the ECU now cuts off the engine if revs drop below a set number to avoid sending shocks through the dual mass flywheel Graham 16, posts months.
Oh yes and when it does hit 2k you have to roll back off the throttle or the bloody thing surges forward Lol, my turbo now kicks in at rpm. Apr 15, Auto Repair Diagnosis.
People choose to buy vehicles with diesel engines for lots of different reasons. For one, the autos typically offer better fuel efficiency than conventional gas-powered cars.
That is a huge draw with what prices at the pumps are these days. The fewer trips a person has to take to the gas station to top off their tanks, the better. Other individuals choose diesel models because of their towing capabilities. Most cars that use gas focus on horsepower.
Meanwhile, diesel engines are all about torque, and they are perfect for pulling heavy loads. Heck, tons of folks even buy diesel vehicles for the reduced maintenance costs. I drove a diesel for many years. I have never driven my diesels any differently to the way I drove the petrol cars — and I never found a problem moving between the different types.
There are four basic combinations when operating the pedals in any normal manual vehicle:. The second option is almost impossible for them to get right every time, and the third and fourth options which the second one turns into if you get it wrong can easily result in stalls. If your instructor is not teaching you to set the gas before finding the bite during normal driving, my advice would be to find another one quickly before you waste too much money.
Most modern cars — petrol or diesel — will move off without it, but not very quickly. Moving off slowly is dangerous, and on test it could easily end up with you failing. There are some very poor instructors out there teaching very questionable stuff. However, if you want to move slowly — during a manoeuvre or when edging out from behind an obstruction, for example — it is perfectly acceptable just to use the bite without any gas if your car will handle it. It depends on the car you are driving.
Just set enough gas that the engine picks up slightly i. Trying to set the gas by numbers creates a delay and distracts you, but setting it by ear and feel is much quicker.
Trying to set 1, revs on the rev counter is very specific and you will begin to focus on adjusting it, whereas just listening and feeling for the engine pick up may well cover a range of as much as 1,, revs in a petrol car on a level surface. The chances are this idea boils down to your instructor trying to save money again.
Also note that the revs are often different between petrol and diesel cars, and the numbers here refer to petrol. Nine times out of ten, all it takes is for the instructor to ask the pupil to touch the gas pedal when he is explaining the pedals. Now get them to touch it as lightly as they can — and to hold their foot still — and ask them to listen to the noise the engine makes.
That sound is what they should be aiming for. You can liken the amount of pressure to trying to squeeze one drop of water out of a wet sponge this works for the clutch, too, when finding the bite , one drop of juice out of a grape or orange and so on. Literally anything that makes sense to the pupil. It often helps to use something that you know they will relate to — playing computer games, football, a musical instrument, and so on.
