Hey guys ,can u just let me know about the most advanced or developed
IC engine.Plz help.
IC engine.Plz help.
Gigabyte111 said:i would have to say that the most advanced IC engine would have to be one that has been converted to run on bio diesel or on keroscene.
just out of curiosity, has anyone seen or heard of a desile engin that incorpeates the technology that disables 1 or 2 pistions so that they are not firing when at idle? or howabout a diesel hybrid (instead of using a gasoliene engine to power the generator. i haven't heard of either of these, but they both seem like they would be a good way to up the MPG's.

I can think of one, but I might be mistaken. Hybrids apparently start and stop the gas motor when the computer determines that extra power or electrical augmentation is needed. With a Diesel, the warm-up time for the glow plugs would cause a serious lag in starting (wouldn't it?)brewnog said:Do you mean a Diesel hybrid car? Don't see any problem with this idea
minger said:They have been doing this for years. I worked at Honda at the time when they were coming out with their design for it. I believe they first put it on the Odyssey. Anyways, they shut down an entire bank of cylinders when under low load. Basically, it used VTEC-like technology to hold the valves open (so there's no loss of power compressing air), then since everything else is computer controlled, it just cuts spark and fuel.

brewnog said:Can anyone be bothered to look up what current glow plugs draw, or think of any other methods of quickly starting a cold Diesel, short of immersion heaters or ether? I suppose it wouldn't be too radical to use the engine when starting the vehicle, and then to start it up periodically during motoring, even if not needed, just to keep some heat in it?
brewnog said:Nope, this is on a spark ignition engine, it's pretty common practice now. I don't know of any CI engines which do it though, anyone?
NateTG said:Not necessarily what you think of under hybrid, but there are definitely industrial vehicles (like locomotives) that run using a diesel generator and electric motors. I think this is primarily because the torque characteristics of electric motors are preferrable.
Googling diesel-electric yields, among other things:

Compressed air is a popular method for starting marine diesels.

Gigabyte111 said:I, in my 12 years of owning many large diesel powered boats/ yachts, I have never in my life encountered a marine diesel started by compressed air, from 15' boats all the way up to a 52' twin turbo diesel powered yacht, have ever heard of a boat started by compressed air, or even have a air compresser on board. i know that for a fact you are required by law (or regulation, not quite sure which) to have atleast two 12v batteries for each engine. it is possible that the lagrer (container ships) ships do this but never in the boats i have had.

Internal combustion engines are considered the most advanced due to their efficiency, power, and versatility. They can be found in a wide range of vehicles and machines, from cars and trucks to airplanes and boats. They also have a high power-to-weight ratio, making them ideal for many applications.
Internal combustion engines work by converting the chemical energy of fuel into mechanical energy. This is achieved through a series of controlled explosions within the engine, which push pistons that ultimately turn the engine's crankshaft. The resulting motion powers the vehicle or machine.
Over the years, there have been many advancements in internal combustion engine technology. Some of the most notable include improvements in fuel injection systems, the use of turbochargers and superchargers, and the development of hybrid and electric engines. These advancements have led to increased fuel efficiency and reduced emissions.
While internal combustion engines are currently the most widely used type of engine, they do have limitations in terms of sustainability. They rely on fossil fuels, which are finite resources, and produce emissions that contribute to air pollution and climate change. However, ongoing research and development in alternative fuels and technology may make these engines more sustainable in the future.
Yes, internal combustion engines can continue to be improved through ongoing research and development. Some potential areas for improvement include increasing fuel efficiency, reducing emissions, and developing more efficient and sustainable fuel sources. Additionally, advancements in technology and materials may lead to lighter and more powerful engines.
