The Engine
Control Module regulates the HPDI System, to ensure superior power, fuel
economy and reliability. Here's how HPDI works. Six sophisticated sensors
help the microcomputer optimize ignition timing and air/fuel mixture. Fuel is
drawn through the fuel pump and vapor separator, then pressurized by the twin
high-speed fuel pumps – to 1,000psi in our new-generation 3.3L HPDI. Proven
and reliable internal-opening fuel injectors distribute the fuel to each
individual cylinder enhancing fuel distribution for increased power and
greater fuel economy. |
3.3L Unique
Features & Benefits |
|
New, Secial Ion-Plated Top Piston Ring enhances durability
and delivers up to 20% more oil economy. The oil bypass groove on the bottom
piston ring delivers the precise amount of oil to the top ring.
|
|
Water Cooled Intake Crankcase This unique feature
increases intake
air density for added horsepower.
|
|
Exhaust Pressure Reduction system reduces
exhaust pressure for increased horsepower and performance.
|
|
Special Heat Treated Crankshaft and Connecting Rods enhance durability
for long term engine life.
|
|
The High Output Alternator on
HPDI 3.3-liter models delivers an incredible 37 amps of charging power at
only 1000 rpm and a full 50 amps at speed. The all new V 76° block is compact
and designed to maximize torque, power, fuel economy and durability.
|
|
New Larger Engine Anodes increase corrosion protection.
|
|
The
3.3-liter, 204 Cubic-Inch Engine. The 76° V-block design is compact, with
added torque for greater acceleration. |
|
Twin High Speed Fuel Pumps pressurize fuel at 1000psi for
outstanding performance and fuel economy on 3.3 Liter HPDI models. 2.6 Liter
models pressurize fuel at 700psi.
|
|
Fuel is Routed through a water/fuel separator, a vapor separator tank, twin high-speed fuel
pumps and fuel rails, then delivered through 6 independent internal opening fuel
injectors.
|
|
Strong, Forged Pistons add
durability. Aluminum alloys are compressed in molds under extreme pressure,
resulting in a much stronger piston.
|
3.3L & 2.6L Features & Benefits |
|
Six Independent Fuel Injectors open internally,
enhancing fuel distribution and reducing the chance of carbon build-up.
|
|
Yamaha's ACP-221 Paint Process provides a 5-layer barrier against
corrosion.
|
|
Stainless Steel is used for the drive, prop and shift shaft
for maximum durability.
|
|
Front-Mounted Freshwater Flushing device makes it easy
to completely flush the engine, in the slip or at home.
|
|
Our exclusive YDC-30 Alloy is the most
corrosion-resistant base material in the industry.
|
|
Our Two Year Limited Warranty protects every HPDI.
|
|
The Proven Homogeneous Combustion Chamber Design maximizes power and
fuel economy in the critical 2500-5500 rpm range.
|
|
The Vapor Separator Tank removes vapors from the fuel for increased engine stability and reliability.
|
|
Counter Rotation dramatically reduces steering torque and arm fatigue, while providing more
control and acceleration.
|
|
Yamaha HPDIs exceed the Federal EPA 2006 emission requirements, and
have earned a California C.A.R.B two-star rating for very low emissions.
|
|
Oil Bi-Pass Groove around the bottom piston ring delivers the precise amount of oil to the top
ring, enhancing durability.
|
|
The Multi-Charge Monitoring System keeps your batteries
charging whenever the engines are running.
|
|
Optional Saltwater Series Prop has extra blade cupping and a high
rake design for superior performance.
|
|
Famed Sure-Seal Tri-Latches seal the cowl tight against water and
salt.
|
|
Precision Blend™ Oil Injection automatically injects just the right
amount of oil, based on load and speed.
|
|
Connect Yamaha's Digital Engine Management System to a
GPS unit and track your mileage, speed and ETA along with your position.
