Dual Fuel Engine
Dual Fuel or DF Engines are the type of engines which can operate 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 as they do not have an ignition system, nor do they have any spark plugs.
As the engine is not a pure diesel engine and diesel is not a pure gas, this machinery does suffer from poor fuel efficiency and Methane slippage. For example, 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 lower or higher loads.
Lift Truck Classification and Fuel Sources
There are certain recycling materials handling applications which could prove very difficult for lift trucks. For instance, scrap metal is amongst these issues. To be able to successfully handle items like this needs using the correct type of machine for the task.
In this write-up, the 7 major lift truck classes are discussed, including the power sources such as liquid propane gas, hydrogen fuel cell, diesel, electric and gasoline. The power source is linked to some of these specific classes. The main power sources for forklifts include Diesel, Gasoline, Battery, Fuel Cell and Propane.
Electric powered trucks are the most popular, mainly Class I, II and class III forklifts. Internal combustion engines are more popular in Classes V and IV. The most popular electric power source is the lead-acid battery. Amongst internal combustion trucks, approximately over 90 percent are propane powered.
The battery is the forklifts most common power source. Battery powered units make up around 60% of the new forklifts sold in the United States. Their benefits include: quiet operation, less maintenance requirements, the ability to be used indoors and outside with no harmful emissions.
