Dual Fuel Engine
Dual Fuel or DF Engines are the kind of engines which could work on a mixture of gas fuel or diesel fuel or it could run on diesel fuel alone. Duel Fuel engines can not run on gas alone because they do not have an ignition system, nor do they have any spark plugs.
Because 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 may be 5% to 8% less than in a comparable spark-ignited, lean burn engine at 100% 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 challenging for lift trucks. For example, scrap metal is amongst these problems. To be able to successfully handle things like this requires using the correct kind of machinery 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 comprise Battery, Diesel, Gasoline, Fuel Cell and Propane.
Electric powered trucks are the most common, 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. Among internal combustion trucks, around over 90% are propane powered.
The most popular power source for lift trucks is battery. Battery powered models make up around 60 percent of the new forklifts sold within the United States. Their benefits include: quiet operation, less maintenance requirements, the ability to be used outdoors and inside with no harmful emissions.
