As a vehicle descends from a high altitude location, the absolute pressure inside the tire remains the same, but the atmospheric pressure increases; therefore the gauge pressure will decrease. Take for example a vehicle which had its cold inflation tire pressure set near Denver (altitude 5300 feet), and is descending towards Los Angeles ...
It also does less damage to the tire surface. This is important on work sites and in agricultural fields; by giving the driver direct control over the air pressure in each tire, maneuverability is greatly improved. Softer tires also cushion against rough terrain and road damage, such as washboarding, more effectively. Reducing tire pressure ...
The first person to build a working four-stroke engine, a stationary engine using a coal gas-air mixture for fuel (a gas engine), was German engineer Nicolaus Otto. [4] This is why the four-stroke principle today is commonly known as the Otto cycle and four-stroke engines using spark plugs often are called Otto engines.
The same rims can usually be used throughout the lifetime of the car. Other problems encountered in tire maintenance include: Uneven or accelerated tire wear: can be caused by under-inflation, overloading or poor wheel alignment. Increased tread wear on only one side of a tire: often a sign of poor wheel alignment.
A tire-pressure monitoring system (TPMS) monitors the air pressure inside the pneumatic tires on vehicles. [1] A TPMS reports real-time tire-pressure information to the driver, using either a gauge, a pictogram display, or a simple low-pressure warning light. TPMS can be divided into two different types – direct (dTPMS) and indirect (iTPMS).
Resurfaced study claims EV tires cause 1,850 times more particulate pollution than gasoline engine exhausts — and California is being slammed for 'trying to conceal' it.
Intake air throttling changes the amount of air sucked into the engine, which means that if a stoichiometric air-fuel mixture is desired, the amount of injected fuel has to be changed along with the intake air throttling. To do so, manifold injection systems have at least one way to measure the amount of air that is currently being sucked into ...
