IDLING SPEED
􀂉-2-stroke engine carburetors are undoubtedly the most polluting, both at idling and maximum speed;
􀂉 4-stroke engines have less HC emissions (-87% compared to 2-stroke engines), but have higher emissions compared to LPG - powered engines (+137,5% compared to an LPG powered engine – 1^ test- +52% compared to an LPG powered engine – 2^ test with enriched gas mixture);
􀂉 LPG-powered engines guarantee the lowest unburned hydrocarbons emissions ( -95%compared to 2-stroke engines and –42% compared to 4-stroke gasoline engines / -92% and –34% compared to LPG engines - 2^ test).
TOP SPEED
􀂉 2-stroke engine carburetors are still very polluting even though emissions from an engine running at top speed are 50% less compared to one running at idle speed.
􀂉 Compared to 2-stroke engines, 4-stroke engines have a better combustion rate and fewer emissions when running at higher speeds (-91% compared to 2-stroke engines). Nevertheless, they still pollute significantly more than an LPG fuelled engine (on average, almost twice as much)
The EFI electronic injection system has improved its performance and lowered dangerous emissions for both the 2-stroke and the 4-stroke engine range.
􀂉 An EFI 4-stroke LPG powered engine running at full speed ensures the lowest emissions (-95/94% compared to a 2-stroke fuel injection engine and – 48/36% compared to a 4-stroke gasoline powered engine).
 

Why choose Power Sea Saver?
The installation of a LPG system in a marine environment requires addressing several issues that differ from those encountered in the automotive sector. In particular, waters with a high salt content require the use of materials that are extraneous to the automotive sector.
Galvanic corrosions generated by stray currents cause lacerations that may compromise the integrity of the system.
Engine vibration, the pressure reducer in contact with the engine (as is the case with outboard engines), electronic parts (trigger box) and electrical parts (fuses and connections) exposed to corrosion, and so on. Power Sea Saver is able to preserve the integrity of engine components over time as it is designed and tested to resist inconveniences such as those listed above. As to fuelling, marine and car engines differ from one another in that the LPG flow in a boat engine occurs at a fairly significant and continuous rate. For example, a boat weighing 8/9 quintals on average, mounted with an 140 HP outboard engine running at a speed of 22 knots (40 km/h) consumes about 0.3-0.5 litres of fuel per minute, whereas, a boat weighing 10-12 quintals mounted with a 250 HP outboard engine consumes about 0.4-0.7 litres of fuel per minute. Therefore, a few adaptations are required to ensure continuous vaporization in an engine with an open loop cooling system. This is possible with Power Sea Saver, thanks to its flexibility and its special features that allow to regulate the system depending on the power required.
