Most modern cars are built with organic acid technology (OAT) antifreeze (e.g., DEX-COOL [25]), or with a hybrid organic acid technology (HOAT) formulation (e.g., Zerex G-05), [26] both of which are claimed to have an extended service life of five years or 240,000 km (150,000 mi). DEX-COOL specifically has caused controversy.
An engine needs different temperatures. The inlet including the compressor of a turbo and in the inlet trumpets and the inlet valves need to be as cold as possible. A countercurrent heat exchanger with forced cooling air does the job. The cylinder-walls should not heat up the air before compression, but also not cool down the gas at the combustion.
On vintage cars you may find a bellows type thermostat, which has corrugated bellows containing a volatile liquid such as alcohol or acetone. These types of thermostats do not work well at cooling system pressures above about 7 psi. Modern motor vehicles typically run at around 15 psi, which precludes the use of the bellows type thermostat.
Carfax said modern cars use electronic fuel injection instead of a carburetor. The system helps promptly deliver the right air-fuel mixture, and your vehicle is ready to hit the road within ...
Device to measure the temperature to which the coolant protects the car from freezing. Water is the most common coolant. Its high heat capacity and low cost make it a suitable heat-transfer medium. It is usually used with additives, like corrosion inhibitors and antifreeze.
Modern car construction and technology can influence longevity. But one crucial factor transcends age: proper maintenance. Regardless if you're cruising in a brand new car or a cherished classic ...
Typical airflow in a four-stroke engine: In stroke #1, the pistons suck in (aspirate) air to the combustion chamber through the opened inlet valve.. A naturally aspirated engine, also known as a normally aspirated engine, and abbreviated to N/A or NA, is an internal combustion engine in which air intake depends solely on atmospheric pressure and does not have forced induction through a ...
Much better than most of the modern cars. The modern cars are brilliant, but they're soulless. "And these have soul. "You get people look at you, wave to you. Over there we have a Fiat Gamine in ...
