What does no ifs ands or buts mean?
—used to indicate certainty As far as I’m concerned, she’s the most qualified candidate, and there are no ifs, ands, or buts about it!
Why do radial engines always have an odd number of cylinders?
The reason that radial engines have an odd number of cylinders is that the firing order is set to fire alternate cylinders, i.e. 1-3-5-7-2-4-6. If there were an even number, there would be two adjacent cylinders that would fire, then the rest would fire in their “fire one-skip one” sequence.
Why are American engines so underpowered?
1. American pushrod engines generally have lower redlines than overhead cam engines. Horsepower is proportional to torque multiplied by rpm, so if you can rev your engine higher and still maintain torque, you can produce more power. The limiting factor to how fast an engine can rev is usually the valvetrain.
Why are new engines more powerful?
Modern engines are more powerful People are more concerned with fuel economy now than when cars were new, but they’re also more concerned with engine power because modern cars are a lot heavier. So today’s engines are more powerful than their predecessors – even compared to engines that are just a few years old.
Do cars lose horsepower as they age?
Some engine power loss is inevitable, Car Throttle explains. As engines get old, their seals get hard and brittle. Piston rings and valvetrain components wear down. This causes compression and horsepower to drop.
Are older cars safer?
The older a car is, the more likely its driver will die in a crash, says a new research paper from the National Highway Traffic Safety Administration. It turns out that a driver of a car 18 or more years old is 71 percent more likely to die in a bad crash than the driver of a car three years old or newer.
Is it safe to drive a 10 year old car?
Safety improves over time. A 20 year old car is safer than a 30 year old car, and of course a 10 year old car is safer than a 20 year old car. In aggregate! 🙂 If passenger safety ratings are (as they should be for the family car) a primary concern, then compare safety ratings between specific vehicles.
