Black smoke from a petrol engine is primarily caused by an overly rich fuel mixture, where too much fuel is being burned compared to the amount of air. This can result from a malfunctioning fuel injector, a clogged air filter, or issues with the engine’s sensors, such as the mass air flow sensor. Inadequate combustion due to poor ignition timing or faulty spark plugs can also contribute to the problem. When unburned fuel exits the exhaust, it creates the characteristic black smoke.

What would happen if diesel is let into a petrol engine or vice-versa?

I assume by gasoline that's the same as unleaded/petrol.... Well basically you will not do any serious damage to the engine itself, the car will stop working, quite possibly have some black smoke coming out the exhaust as the diesel works it way through, you will not be able to use the car until the entire fuel system has been drained out, so its a costly and frustrating mistake to make.


Why was the steam engine invented in 1780?

James Watt watched a tea kettle boil, and built a steam engine. This is what we read in school. But England imported tea from China; the Chinese have boild tea for a thousand years before the English. Why didn't some Chinese James Watt invent the steam engine?Karl Benz built the first petrol engine car in Germany, a hundred years after Watt. Nobody boils tea in petrol, so what inspired Karl Benz?From Steam to PetrolJames Watt's steam engine, was NOT inspired by a tea kettle, but by earlier steam engines by Thomas Savery and William Newcomen. But theirs were inefficient engines - Watt's major breakthrough took twenty years of hard work and several incremental improvements, mainly in mesuring devices. His crucial breakthrough was an external condenser. Watt's stationary engine, powered cotton mills and mechanical presses in the 1780s. The railway steam engine, was invented forty years later by Richard Trevithick and George Stephenson in the 1820s. Scientific discoveries about heat and power - the field of thermodynamics. Petroleum was discovered only in the 1850s, primarily used for lighting lamps or stoves.But some tinkering engineeers saw great potential in petrol, as a substitue for steam engines. Coal was hard to mine, slow to ignite, difficult and dirty to handle and caused a lot of smoke and grime; petrol on the other hand, flowed from oil wells, could be stored in tanks, flowed through pipes and had a much lower ignition point.The EngineThe petrol engine was invented by Nikolaus Otto, a travelling salesman for a food company! He had been inspired by an engine designed by Lenoir that ran on coal gas; Otto experimented with a copy of a Lenoir engine that another skilled mechanic built for him in 1861. He created an engine fueled with an alcohol air mixture. Eugen Langen owner of a sugar refinery, invested in a new company that Otto started, and he built an improved engine. At the 1867 Paris exhibition, his engine won the first prize. He expanded this company, reorganized as Gasmotorenfabrik Deutz AG.. This was not a car engine, but more like a mechanical power device for workshops, like printing presses.Otto hired Gottlieb Daimler and William Maybach to improve it; they made it smaller, quieter, more efficient. But when Daimler proposed fitting Otto's engine to power a horseless carraige, Otto showed no interest.


Why yellow smoke from diesel generators?

Yellow smoke from diesel generators typically indicates incomplete combustion of fuel, often due to insufficient air supply or fuel quality issues. It can also result from using contaminated or degraded fuel. Additionally, poor engine tuning or malfunctioning injectors can contribute to this problem. Addressing these issues is essential to improve efficiency and reduce emissions.


What does a smoke stack do on a steamship?

A smoke stack on a steamship vents exhaust from the ship's boiler to the air outside.


What happens if your smoke detectors goes off but there's no smoke?

This may because specs of dust can cause activation of the detector as it has the same effect as smoke. Spiders also can crawl into the sensors which does the same thing- same way with deodrant, paintfumes etc. It also may be because the smoke detector is just faulty.
