Dual Fuel Engine
Dual Fuel or DF Engines are the type of engines which could run on a mixture of diesel fuel and gas fuel or it could operate on diesel fuel alone. Duel Fuel engines could not operate on gas alone since they do not posses an ignition system, nor do they possess any 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 Methane slippage as well as fuel efficiency.. Like for instance, the fuel efficiency may be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100% load. It could even be lower or higher loads.
Lift Truck Classification and Fuel Sources
There are certain applications that have proved difficult for the forklift. For example, scrap metal is one of these problems. In order to successfully handle things like this needs using the right type of machine for the job.
There are 7 major lift truck classes, including power sources such as liquid propane gas, hydrogen fuel cell, electric, gasoline and diesel. The power source is linked to several of these specific classes. The main power sources for forklifts consist of Diesel, Gasoline, Battery, Propane and Fuel Cell.
Electric powered trucks are the most popular, mostly Class III, III and class I forklifts. Internal combustion engines are more popular in Classes V and IV. The most common electric power source is the lead-acid battery. Amongst internal combustion trucks, around over 90 percent are fueled by propane.
The battery is the forklifts most popular power source. Battery fueled models make up around 60% of the new forklifts sold within the USA. Their benefits consist of: quiet operation, less maintenance requirements, the ability to be used outside and indoors with no harmful emissions.
