What is the largest advantage and disadvantage of a radial engine?
The radial engine has the lowest weight-to-Hp ration of all the different types of piston engines. It has the disadvantage of greater drag because of the area presented too the air. The V-type engine has the cylinders arranged on the crankshaft in two rows forming a V.
How much horsepower can a radial engine generate?
A typical radial engine in a B-17 has nine cylinders, displaces 1,800 cubic inches (29.5 liters) and produces 1,200 horsepower. Radial engines have a relatively low maximum rpm (rotations per minute) rate, so they can often drive propellers without any sort of reduction gearing.
What is the primary disadvantage of a radial engine?
A potential disadvantage of radial engines is that having the cylinders exposed to the airflow increases drag considerably. The answer was the addition of specially designed cowlings with baffles to force the air between the cylinders.
Is a 2800 a radial engine?

How much horsepower does a semi truck engine have?
The engine of a semi-truck is up to 6 times larger than that of a car engine in both size and weight. The average semi engine has 400-600 horsepower and around 1-2 thousand FT.LB or torque versus 100-200 horsepower and 100-200 FT.LB of torque. Semi Engines, as opposed to car engines, are designed to run stop.
What are the strongest Diesel semi truck engines?
There are some pretty impressive diesel semi truck engines on the market that have a lot of power behind them. Here are some of the strongest truck engines around. DAF XF: This Dutch-made, 12.9-liter, 6-cylinder engine boasts 510 hp and up to 2500 Nm of torque giving it some impressive hauling power.
Are semi trucks reliable?
Semi trucks have become increasingly reliable over the years and true breakdowns aren’t as common as they used to be. However, nothing will kill your profit in the trucking industry like experiencing downtime. So, while it’s good to know which engines to choose, you should also know which ones to avoid.
Do wider tires make a difference on diesel trucks?
“As diesel engines develop more torque than typical gas engines, wider tread patterns can prove particularly helpful to diesel truck owners seeking extra grip,” he said. “That extra diesel torque can also cause tires to wear more quickly, so going with a wider and deeper tread enables the tires to last longer and be replaced less frequently.”
