But bigger engines, which weigh more and cost more to build and maintain, are not always better. Another way to add power is to make a normal-sized engine more efficient. You can accomplish this by forcing more air into the combustion chamber. More air means more fuel can be added, and more fuel means a bigger explosion and greater horsepower. A turbo/supercharged engine produces more power overall than the same engine without the charging. Both superchargers and turbochargers do this. The difference between the two devices is their source of energy . TURBOCHARGER When people talk about race cars or high-performance sports cars, the topic of turbochargers usually comes up. Turbochargers also appear on large diesel engines. A turbo can significantly boost an engine's horsepower without significantly increasing its weight, which is the huge benefit that makes turbos so popular! . In fact, the
• First electric cars were produced in 1880s • Were popular in 19th and 20th cebtury •Then ICEs became more advanced Advantages • 3 x more efficient as ICE • Quieter • Do not emit tailpipe pollutants • Instant, strong and smooth acceleration • Lower running costs • Government discounts Disadvantages • Battery wears out over time • Batteries are expensive • Limited driving range (best range Tesla S – about 400km) • Charging takes a long time (unless using superchargers) • Lack of charging stations • Cost a bit more than ICE cars • Manufacturing produces heavy checmical waste Disadvantages • Effects on human health are unknown • It is believed that these kind of powerful batteries might be dangerous Popular Evs – Mitsubishi i-MiEV Popular Evs – Nissan Leaf Popular Evs – BMW i3 Popular Evs – Tesla S Popular Evs – Tesla Model 3 Thank you!
