Can you gas convert a diesel engine

Given the low overall savings achieved to date and the cost of the adaption often equal to that of an injected Petrol engine conversion many miles would have to be covered before any real savings are realised whilst reliability has been reduced. This does not seem to be an economically viable alternative. As world Diesel prices continue to rise sharply, there may be more economic benefit in mixing LPG with Diesel. We are still waiting to see a system that works well and comes with audited figures for reliability and the cost savings achieved.

If such a system comes along, with UK LPG accreditation, we'll do some long-term evaluation before a decision is made to offer it to our customers. Benefit becomes Burden There are some other benefits apart from saving fuel cost. The classic Diesel 'Knock' can be greatly reduced.

The main reason for increased smoothness and reduced noise vibration is that the LPG element begins its combustion before the Diesel fuel does, a result of 'detonation' due to the compression ratio being so high.

The engine may also get up to its optimium temperature more quickly, whilst harmful emissions like Particulates and Carbon Monoxide can be reduced. These all appear to be benefits.

Sadly, a new set of problems arise when the Driver begins to use the increased performance of an engine that wasn't designed to rev to the new, higher levels. Conclusion On a purely fuel cost-reducing basis this adaption or fumigation system does not appear to be an attractive or useful alternative for the average Diesel motorist. That doesn't mean that the people working on these projects should stop, we hope they succeed.

Perhaps their research will continue and go on to give us all a better solution. Though there are significant differences in how these engines generally operate, and huge differences in what each respective fuel likes inside of the combustion chamber. For those unfamiliar with the wild adventures of Garage 54 , the team has tackled making clear engine covers to show us how oil operates in an engine , welded two cars together and put hilariously undersized wheels and tires on a Hummer.

This wacky YouTube channel has tackled some interesting problems but has yet to tackle an engineering experiment like this. The Garage 54 folks compression test a diesel-burning Toyota four-cylinder engine, to find that it has at least one damaged cylinder. Even with that damaged cylinder, this diesel engine has far too much compression to make gasoline not detonate. The Garage 54 team then tear down the engine to measure the combustion chambers.

Basically, you need to make more space between the piston and the combustion chamber. You can tackle this problem by replacing pistons, changing the cylinder head, or thicker head gaskets. Of course, best-case scenarios rarely happen in the Garage 54 shop, and the team decided to modify the pistons in their engine to lower the compression ratio.

The engine will continue to use diesel fuel for compression ignition, but will get most of its power from natural gas. Natural gas is widely hailed as cleaner than other fossil fuels, but new research says using it — instead of diesel — to power trucks and buses could actually exacerbate global warming over a year period. But from a climate perspective, "it's not likely to reduce greenhouse gas emissions.

To convert among any units in the left column, say from A to B, you can multiply by the factor for A to convert A into Joules then divide by the factor for B to convert out of Joules. While a gallon of LNG generally is less expensive than a gallon of diesel , natural gas contains less energy than does diesel per unit volume.

Although LNG can be produced readily at competitive rates, the costs of supplying LNG often depend on transportation expenses. A good way to save on gas costs is to convert your vehicle to natural gas. Though most cars that have been converted to natural gas run off of CNG compressed natural gas , you can change you engine to run off of propane or liquefied natural gas LPG.

Getting your car converted to run on LPG may not affect your insurance premium, but you will need to inform your insurance provider of the changes made to your car as it is classed as an engine modification.

Federal government figures show demand for LPG in the 12 months to 30 June dropped 8 per cent off the back of a 4. If your car is not fuel efficient, then converting to LPG is certainly worth considering. If the initial outlay is making you hesitate, then consider that within two years it will have paid for itself if you cover around 15, miles each year. Although cars are unlikely to be more fuel-efficient when running on LPG , you could still soon halve your fuel bills. Each tank about 9.

Running costs on gas — we still use a little petrol per tank — have been 12p a mile, compared with 17p if running purely on petrol. This kit contains the gas jets needed to convert your hob from natural gas to LPG.

Propane burns cleaner and cooler, and in turn your engine runs cleaner, cooler and longer. The engine's response is quick, smooth and powerful. The idea of injecting propane as a secondary fuel in turbo diesel engines has been widely used for many years and is not a new idea. Kerosene will burn in a diesel engine without causing serious damage, but it is not efficient.
