Dual Fuel Engine
Dual Fuel or DF Engines are the type of engines which could work on a mixture of diesel fuel and gas fuel or it can operate on diesel fuel alone. Duel Fuel engines could not run on gas alone as they do not have an ignition system, nor do they have any spark plugs.
Since 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 example, the fuel efficiency could be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100% load. It can even be greater on lower loads.
Lift Truck Classification and Fuel Sources
There are some applications which have proved difficult for the forklift. For instance, scrap metal is amongst these problems. In order to successfully handle items like this requires using the right kind of equipment for the task.
There are 7 major lift truck classes, including power sources like liquid propane gas, hydrogen fuel cell, electric, gasoline and diesel. The power source is linked to some of these specific classes. The main power sources for forklifts comprise Battery, Diesel, Gasoline, Fuel Cell and Propane.
Electric powered trucks are the most popular, mostly Class I, II and class III 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 propane powered.
The battery is the forklifts most common power source. Battery fueled units make up around 60 percent of the new forklifts sold in the USA. Their benefits include: less maintenance requirements, quiet operation, the ability to be used outdoors and inside with no harmful emissions.
