Dual Fuel Engine
Dual Fuel or DF Engines are the type of engines which can work on a mixture of gas fuel or diesel fuel or it could work on diesel fuel alone. Duel Fuel engines can not run on gas alone because they do not have 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.. For example, the fuel efficiency could be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100% load. It could even be greater on lower loads.
Lift Truck Classification and Fuel Sources
There are certain recycling materials handling applications that could prove very difficult for lift trucks. Like for example, scrap metal is one of these problems. To be able to successfully handle things like this requires using the correct type of equipment for the job.
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 several of these specific classes. The main power sources for forklifts include Battery, Diesel, Gasoline, Propane and Fuel Cell.
The most popular overall are electric powered trucks, mostly in Class I, II and class III forklifts. In Classes IV and V, internal combustion trucks are more popular. The most popular electric power source is the lead-acid battery. Amongst internal combustion trucks, approximately more than 90% are propane powered.
The battery is the forklifts most common power source. Battery fueled units make up roughly 60 percent of the new forklifts sold in the USA. Their benefits consist of: less maintenance requirements, quiet operation, the ability to be utilized outdoors and indoors with no harmful emissions.
