Any engine will lose RPM going up a hill, its called gravity and the engine has to overcome it. The heavier the vehicle the more RPM you lose. Thats also why transmissions have all the extra gears. Lower gear equals more pulling power and less speed, higher gear is less pulling power and more speed.
What else can I help you with?
Does a diesel engine require more oxygen than a gasoline engine?
Yes a diesel engine requires a lot more air than a gasoline. The ratio for air to fuel in a gas engine is about 14.7:1. A diesel at idle is about 50:1 and in the higher rpms it can reach 70:1.
Which is more powerful petrol or diesel engine?
Normally Diesel engines produce more torque than gasoline engines but less horsepower. Gasoline engines rev up quicker and produce higher horsepower at higher rpms. Diesel engines develop their higher torque at lower rpms which allows a diesel to carry a heavier load.
What would make a 2000 expedition 5.4 lts engine rpms going up and down when you are stop and sometime the rpms goes between 500 and 1000 rpms?

Which is faster diesel engine car petrol engine car if same power same cc engine is used which will move faster?
It really comes down to power-to-weight, gear ratios, etc. The notion that diesel vehicles are significantly heavier or that diesels top out at lower RPMs isn't necessarily true...while there are gasoline engines which can run 15,000+ RPMs, they're not representative of a "typical" gas engine. Diesel vehicles have substantially higher torque, wider powerbands, and higher thermal efficiency, which can very easily give a diesel engined variant of a car a significant advantage over a gasoline powered version.
Are high RPMs when driving uphill in cruise control bad for your car engine?
It depends how high you're talking about. If you mean revving all the way to the red line then yes this is bad for the engine. But the rpm shouldn't exceed 4000 rpm. If it is slightly below this then it is fine.
Is gas engine more reliable than diesel in pickups?
No, diesel engines run with lower rpms and which also causes them to have lower tempuratures. diesel engines in semi trucks get up to 1,000,000 miles in them with just simple rebuilds. gas engines are a disiaster with over 150,000 miles.
Why do automobiles engines idle 6000 rpms?
If you have an engine that idles at 6000 rpms, you need to have it checked - immediately. Around 750 rpms would be normal.
What is the torque of a 60 hp VW engine?
The 60-horsepower VW engine has a torque specification of 115 pounds at 2000 RPMs. The engine will have 130 pounds of torque at 2500 RPMs.
What is the diesel consumption rate of a tractor?
That would depend on the displacement, rpms and the load it is be asked to bear.
Is house power 183 hp 6300 RPM better than 173 hp 5600RPM?
No. You are not going to be running an engine at over 6,000 rpms.
Why are diesel engine standard in heavy machinery and freight application?
Diesel engines have more torque especially at low rpms. This gives them much more pulling power. They also last much longer that gasoline engines. require less maintenance, and get better fuel economy.
