Does a mechanical engineer build cars
It's available in standard and MAX configurations and is just as off-road capable as the civilian version. The police-duty Expedition is shipped with the turbocharged, 3.5-liter V6 EcoBoost engine, which delivers 400 horsepower and up to 480 pound-feet (651 Nm) of torque.
Cars are expensive to operate, especially with the cost of gasoline on the rise. Repair costs vary widely by model and location, but most engine rebuilds or replacements will run thousands of dollars, meaning you'll want to do everything you can to extend your engine's life as long as possible. Some of these tips are things you'll want to do while behind the wheel, while others are maintenance tasks you can do yourself or enlist a professional mechanic to do for you.

One of the diesel valve adjustment symptoms is pre-ignition. This condition occurs when the fuel inside the combustion chamber ignites all by itself, even before the spark plug can initiate.
Chart: Cars waste most of the energy we feed them in fuel. Left: In stop-start city driving, only about 17 percent of the energy in gasoline (green slice) provides useful power to move you down the road. The other 83 percent is wasted (red slices) in the engine, in parasitic losses (in things like the alternator, which makes electricity), and in the drivetrain (between the engine and the wheels). Right: Things are a bit better on the highway, where useful power can nudge up to 25 percent or slightly more. Even so, the bulk of the energy is still wasted.

Fuel Choice : Avoid using synthetic oils, as they can leave deposits that can damage the apex seals. Instead, opt for high-quality conventional oils or consider using a mix of 2-stroke oil and gasoline to help lubricate the apex seals. Oil Injection Modification : Some owners choose to modify the oil injection system to use TC-W outboard oil, which can reduce oil consumption and improve overall lubrication.
The dull knock.
