Advantages over Diesel• Positive
Ignition(More Precise
Control)• Lower Compression
(Increased Output)• Lower Firing
Pressures(Less
Strain)• Light Weight
(Less Expensive Parts)• Less
Momentum(Higher
Speed)• Less Vibration
(Less Expense to Install)• Less
Noise(More Efficient
Energy)• Easy Cold Start
(+ Ign & Low Compression) • Multi
Fueled(Gasoline, Natural Gas, LPG,
BioGases)
Disadvantages From Diesel• Less
Efficient(Power and Energy)
• Less Durability
(Gasoline Wash Less Lube)• Electric System
Ignition(1 More
System)• Light Weight Parts
(Less Torque/Lug)• Less
Momentum(Lower Continuous
Power)• 2 Cycle Emissions(Diesel Cleaner – Lube)• Boost
Restrictions(Fueled
Intake/Explode)• Less Rebuildable
