The engine efficiency is less than when the engine is operating at full throttle. One solution to this issue is to shift the load in a multi-cylinder engine from some of the cylinders (by deactivating them) to the remaining cylinders so that they may operate under higher individual loads and with correspondingly higher effective compression ratios.
Underinflated tires wear out faster and lose energy to rolling resistance because of tire deformation. The loss for a car is approximately 1.0 percent for every 2 psi (0.1 bar; 10 kPa) drop in pressure of all four tires. [7] Improper wheel alignment and high engine oil kinematic viscosity also reduce fuel efficiency.
The startup time for a steam car may take up to 45 minutes, defeating the purpose of faster transportation. By the time the steam automobile was improved, the complexity of manufacturing relative to the gas automobiles made steam automobiles unprofitable. [5] A steam engine is a device which transforms heat into mechanical motion.
Hydrogen fuel enhancement from electrolysis (using automotive alternators) has been promoted for use with gasoline-powered and diesel trucks, [14] [15] [16] although electrolysis-based designs have repeatedly failed efficiency tests and contradict widely accepted laws of thermodynamics (i.e. conservation of energy).
Sanchez, who previously worked on gas-powered cars and now focuses on EVs, said it can cost less to repair a water damaged EV than a car with a combustion engine - if you are lucky.
Lean-burn gas engines are almost always turbocharged, resulting in high power and torque figures not achievable with stoichiometric engines due to high combustion temperatures. Heavy duty gas engines may employ precombustion chambers in the cylinder head. A lean gas and air mixture is first highly compressed in the main chamber by the piston.
Ferrari is full speed ahead on its first electric car—and the CEO promises it’s going to roar just as loud as a combustion engine Sasha Rogelberg Updated September 28, 2024 at 10:00 AM
A post shared on Facebook claims Tesla CEO Elon Musk announced the creation of a water-powered car engine. Verdict: False There is no evidence Musk has announced such a creation. Fact Check: Tesla ...
