What is the difference between Volvo XC60 T5 and B5?
1 Answers
Volvo XC60 T5 and B5 differ in their engines. The Volvo B5 engine is equipped with a 48V mild hybrid system, while the T5 engine does not have this feature. The B5 engine also features an improved automatic start-stop system. The T5 has a maximum horsepower of 254, whereas the B5 reaches 250 horsepower. Below is an introduction to engines: 1. External combustion engine: An external combustion engine burns fuel outside the engine. Invented in 1816 by R. Stirling of Scotland, it is also known as the Stirling engine. The engine converts the thermal energy generated by this combustion into kinetic energy. The steam engine improved by Watt is a classic example of an external combustion engine. When a large amount of coal burns to produce heat that turns water into steam, high pressure is generated, which then drives mechanical work, completing the conversion of thermal energy into kinetic energy. 2. Jet engine: This type of engine generates thrust directly by the high-speed jet of gases expelled from a nozzle. It is widely used as a power source for aircraft. Fuel and oxidizer undergo chemical reactions in the combustion chamber to release thermal energy, which is then converted into the kinetic energy of high-speed airflow in the nozzle. Rocket engines, which carry their own oxidizer, include solid-fuel and liquid-fuel rocket engines.
