Dual Fuel Engine
The Dual Fuel engine is a kind of engine which utilizes a mixture of diesel fuel and gas fuel or could operate off of diesel by its self. The dual fuel engine is not capable of working on gas alone. These engines do not have ignition systems and do not use spark plugs.

Because diesel is not a pure gas, and it is not a pure diesel designed engine, it has some disadvantages in the department of fuel efficiency, as well as Methane slippage.. Like for example, the fuel efficiency may be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100% load. It could even be lower or higher loads.

Lift Truck Fuel Sources and Classifications
There are some applications that have proved a challenge for the forklift. Like for instance, scrap metal is among these issues. To be able to successfully handle items like this needs utilizing the correct type of equipment for the job.

There are 7 major lift truck classes, including power sources like hydrogen fuel cell, liquid propane gas, gasoline, diesel and electric. The power source is linked to some of these particular classes. The main power sources for forklifts consist of Gasoline, Battery, Diesel, Fuel Cell and Propane.

Electric powered trucks are the most common, mostly Class I, II and class III forklifts. Internal combustion engines are more common in Classes V and IV. The most common electric power source is the lead-acid battery. Out of internal combustion trucks, about more than 90% are fueled by propane.

The battery is the forklifts most popular power source. Battery powered units make up roughly 60% of the new forklifts sold within the USA. Their benefits comprise: less maintenance requirements, quiet operation, the ability to be used outdoors and indoors with no harmful emissions.
