Why is the RPM of a tractors engine lesser than a car's diesel engine, and produce less HP as compared to cars despite having more CC?
This has to do with rev band to get vehicle speed. An industrial, marine or agricultural diesel engine is all about torque and the car engine all about speed.If you could imagine driving a car that reved to just 2000rpm and you want to drive on the autostrade at 130km/hr. You would need a lot of gear ratio change steps to get the vehicle from rest to 130kms/hr. The revs of a modern car diesel at this speed will be around 2500 to 3000rpm.Tractors you choose a speed that is suitable for the implement you are using and leave the engine with a hand throttle running at its rated rpm which gives the standard PTO speed of 540rpm. The engine has a lot of torque just runs at this rpm all day. The operator just needs to control the implement and steering. There are a lot of gears in a tractor but many of them never get used.A boat just chugs along at its rated speed in knots being mindful of wash and channel speeds and a lot run at speeds less than 1000rpm. The diesel engines huge torque output and low stress design means they often run for 30–60years.Your comments about HP. This is a missleading rating for an engines ability to do a job. HP was often used in blatant advertising material for cars where statements like “ this updated model puce has 10bhp more than last years model and will out accelerate yuk brands goose model”. This made you rush out and buy it cause you could now burn off your neighbour at the lights. HP is a function of torque by RPM so if the engine has its torque band moved up the rpm band it will produce more HP but wont pull on long hills in low gear as another engine with the same torque value but at lower rpm and less HP at higher rpm. The latter may have a higher top speed on the flat at the expense of fuel consumption.
Which type of gears are used in tractors?
The mechanism of the engine is a combination of the differential assembly parts[1] The smartness of the engine depends on the preciseness of the parts. The perfect setting and compatibility with the central system make the whole mechanism appropriately active.The Activity of the CombinationThe combination influences the engine in a below-mentioned manner-It transmits the power from the drive shaft to the running wheels.It is responsible for the final reduction of the gears.It carries the amount of torque, which gets a transfer to four wheels.It plays a vital role in the rotating and turning of the wheels.In this way, the combination of the differential assembly parts[2]plays a key role in the movement of the vehicle.The components that assemble the mechanism are like the following-1. Pinion GearIt transforms the power to the ring gear from the drive shaft.2. Assembly CaseThe combining components are assembled inside a container. It keeps the parts in the correct setting.3. Ring GearThis component transmits the power to the combining case, so that drive the mechanisms rightly.4. Rear AxelsIt transmits the torque from the combining case to the drive wheels.5. Drive ShaftIt helps in rotating the pinion.6. Side GearsIt helps the wheels to turn independently.The Importance of the CombinationA vehicle has to take various speeds and turns during the drive. Therefore, the inner wheels tend to move at a high rate than the outer wheels. And at the same time, the vehicle has to maintain a safe distance of the preceding vehicle. The proper control is needed under this circumstance. Power is essential for this situation. The differential assembly parts[3] help efficiently in transferring the powers to form the engine to the wheels.Footnotes[1] Sona BLW Global Products[2] Sona BLW Global Products[3] Sona BLW Global Products
What is creeper gear in agriculture Tractor ? Used for what?
Some farm implements require you to drive very slowly yet with high engine revolutions per minute in order to have the PTO shaft spin at the proper rpm needed to drive the implements mechanism at the desired speed.
Is there a generator that can be powered by automobile or truck wheels and generate 100 horsepower in electricity?
A car dyno could be used but why wear out the tires, drive line and dyno when the engine can just drive the generator directly.An eddy current dyno is basically a shorted out generator just swap it out for a 75 kw generator and match the throttle setting to the load with a governor.Some 4 wheel drives and trucks have a PTO that can drive pumps and welders if they are rated for the hp no problems.
