In the early years, steam engines and electric motors were tried, but with limited success. In the 20th century, the internal combustion engine (ICE), became dominant. In 2015, the internal combustion engine remains the most widely used but a resurgence of electricity seems likely because of increasing concern about ic engine exhaust gas emissions.
Dr. Dinesh Prasad Saklani is the director of NCERT since 2022.

Vehicle dynamics is the study of vehicle motion, e.g., how a vehicle's forward movement changes in response to driver inputs, propulsion system outputs, ambient conditions, air/surface/water conditions, etc. Vehicle dynamics is a part of engineering primarily based on classical mechanics.
The ILMOR-Chevrolet Indy V6 engine is a 2.2-liter, twin-turbocharged, V-6 racing engine, developed and produced by Ilmor Engineering for the IndyCar Series.Chevrolet has been a highly successful IndyCar Series engine supplier since 2012, scoring 100 IndyCar wins, 35 pole positions, 7 IndyCar Series driver's titles and 7 IndyCar Series manufacturer's titles.
The term internal combustion engine usually refers to an engine in which combustion is intermittent, such as the more familiar two-stroke and four-stroke piston engines, along with variants, such as the six-stroke piston engine and the Wankel rotary engine. A second class of internal combustion engines use continuous combustion: gas turbines ...
The London Science Museum's difference engine, the first one built from Babbage's design. It has the same precision on all columns, except in calculating polynomials, the precision on the higher-order columns could be lower. A difference engine is an automatic mechanical calculator designed to tabulate polynomial functions.
Engine braking is a generally accepted practice and can help save wear on friction brakes. It is even used in some motor sports to reduce the risk of the friction brakes overheating. Additionally, fuel injection engines generally do not use fuel while engine braking. This is known as deceleration fuel cut-off (DFCO).
Originally an experiment in creating a fuel-saving automobile in the United States, the vehicle weighed only 135 lb (61.2 kg) and was an adaptation of a small gasoline engine originally designed to power a bicycle. [12] The fuel economy of an automobile relates to the distance traveled by a vehicle and the amount of fuel consumed. Consumption ...
