Dual Fuel Engine
Dual Fuel or DF Engines are the type of engines which could run on a mixture of gas fuel or diesel fuel or it could run on diesel fuel alone. Duel Fuel engines are not able to run on gas alone because 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 instance, the fuel efficiency could be 5% to 8% less than in a comparable lean-burn, spark-ignited engine at 100 percent load. It can even be greater on lower loads.
Lift Truck Fuel Sources and Classifications
There are some recycling materials handling applications that could prove very difficult for lift trucks. Like for instance, scrap metal is amongst these problems. To be able to successfully handle things like this requires utilizing the right type of machine for the task.
There are 7 major lift truck classes, including power sources such as hydrogen fuel cell, liquid propane gas, diesel, electric and gasoline. The power source is linked to several of these specific classes. The main power sources for forklifts comprise Battery, Diesel, Gasoline, Fuel Cell and Propane.
Electric powered trucks are the most common, mainly 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. Among internal combustion trucks, about over 90 percent are propane powered.
The most popular power source for lift trucks is battery. Battery powered units make up around 60 percent of the new forklifts sold within the United States. Their benefits consist of: quiet operation, less maintenance requirements, the ability to be used inside and outside with no harmful emissions.
