SUMMARY

The forum discussion centers around a debate regarding engine load during acceleration in different gears. Participants argue that accelerating in a lower gear, such as 3rd gear, imposes a greater load on the engine compared to higher gears like 5th gear, particularly when considering factors like gear ratios and wind resistance. The discussion highlights misconceptions about engine load, particularly the claim that load remains constant regardless of the incline or gear. Key points include the impact of RPM and the relationship between load and engine wear.

PREREQUISITES
  • Understanding of engine mechanics and load dynamics
  • Familiarity with gear ratios and their effects on performance

NEXT STEPS
  • Research "Gear Ratio Effects on Engine Load" to understand how different gears impact performance
  • Study "Physics of Engine Load and Acceleration" for a deeper grasp of the underlying principles
  • Learn about "Wind Resistance and Its Impact on Vehicle Performance" to see how external factors affect engine load
  • Explore "RPM and Engine Wear" to understand the relationship between engine speed and longevity
USEFUL FOR

Automotive enthusiasts, mechanics, and anyone interested in understanding engine performance dynamics and load management during acceleration.

Settle and argument between retards :)

basically is a car forum with a guy on there NO ONE can convince.

he does not understand the concept of load put on let's say an engine.

for example, accelerating up a hill, would put more of a load on the engine, rather than accelerating on a flat surfce.

the argument is basically, accelerating in 5th gear puts more of a load on the engine than let's say 3rd gear, which is definatly correct. because the lower gear ratio, amoungst other factors (wind resistance at high speeds, ect) generate a larger load on an engine therefore making it more prone to high temps/detonation/ect...

all common knowledge, but he won't understand. i was hopefully someone who is a real physics wiz would be able to explain this in terms this kid could understand.

thanks, here is some quotes from him LOL


Your engine has the same load whether your going up a 45 degree angle or on a flat road. Why can't you understand this?

I was talking about you and rogue, you are still completely wrong. You are not partially correct whatsoever. Load increases only when you step your foot on the gas peddal further. Load can't increase if your peddal is to the floor.

No matter what ****in type of load it is. Whether its the map sensor reading, or physical load on the crankshaft.

the truth is neither one of you understand,

At Wide Open throttle...the load on your engine is the same whether your in 4th gear or 5th gear.

Tell that to anybody with intelligence and they will agree

hp output is the definination of load, hp stays constant.

if u r already going 70mph and starts to accelerate in 5th gear it won't put that much "load" as if u try to accelerate it while going 20mph, coz of friction, kinetic energy and viscous drag.i don't what is his point of view.
but RPM can be held responsible for wearing down engine more that load coz in an engine with a given amount of fuel the pressure is almost always the same. but exessive load will damage the crank shaft and the gears because of coupling of torques, one for the engine itself and other from the load.
