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
