Husqvarna TE150i 2022

Engine

Using the latest 2-stroke fuel injection technology, the TE 150i has all the convenience of a modern 4-stroke as it eliminates the need to premix fuel or adjust jetting at different altitudes. The engine uses specific shaft arrangements designed to harness the rotating mass of the engine in the ideal centre of gravity. The lightweight and compact engine provides strong power delivery tailored for enduro riding while retaining low-cost 2-stroke maintenance.

Cylinder and piston

The cylinder features a 58 mm bore and an innovative power valve design that delivers controllable power throughout the RPM range. The piston is designed to perfectly match the combustion chamber contour delivering the highest level of 2-stroke performance.

Additionally, the cylinder features two inlet positions located on the transfer ports at the rear of the cylinder where a pair of fuel injectors are mounted. The injectors deliver the fuel downwards into the transfer port which guarantees excellent atomisation with the air travelling upward to the combustion chamber. This ensures more efficient combustion resulting in reduced fuel consumption and emissions.

Crankshaft

With a 54.5mm stroke, the crankshaft is perfectly balanced to reduce vibrations. The weighted flywheel attached to the crankshaft provides abundant torque and controllable power tailored for enduro riding while the large alternator provides all the power needed for the EFI system.

Crankcases

The crankcases are manufactured using a high-pressure die-cast production process resulting in a thin wall thickness and minimal weight. To centralise mass, the layout features a shaft arrangement precisely positioned to harness rotating masses at the ideal centre of gravity. The reed block features optimised carbon reeds for improved sealing.​

Oil tank and pump

The TE 150i features an electronic oil pump which feeds vital 2-stroke oil into the engine to keep it lubricated. The pump is located just below the oil tank and feeds the oil via the throttle body meaning the oil is not mixed with the fuel, eliminating the need for pre-mixing as on traditional 2-stroke engines. The pump is controlled by the EMS and delivers the optimal amount of oil according to the current RPM and engine load, reducing waste and preventing excessive smoke being transmitted from the exhaust.

The oil tank is located beneath the fuel tank and is connected to a filler hose which runs through the upper member of the frame to a filler cap conveniently located for easy refills. The tank capacity is 0.7 litre and is fitted with a sensor which illuminates a warning visible to the rider when the oil needs to be refilled.

Gearbox

The TE 150i is fitted with a Pankl Racing Systems 6-speed wide range gearbox. The enduro-specific ratios are tailored to the 150cc power delivery while an innovative gear level reduces dirt build up ensuring perfect operation in all conditions.

DS clutch

The TE 150i features a DS (Diaphragm Steel) clutch. The exclusive characteristics of this system include a single diaphragm steel pressure plate instead of traditional coil springs. The clutch basket is a single-piece CNC-machined steel component that allows the use of thin steel liners and contributes to the compact design of the engine.
