1903 – Motorcycles The first motorcycle, which could reach the impressive speed of 4–5 km/hour, was produced in 1903. Starting in the 1930s, Husqvarna's lightweight engines helped make some successful track racing and motocross bikes. Husqvarna's first titles in Motocross World Championship came in 1959 and 1960.
Husqvarna was founded near the town of Huskvarna in Sweden in 1689. [3] The company started out as a maker of muskets, and the Husqvarna logo still depicts a gun sight viewed from the end of the barrel. [3] [4] As with many motorcycle manufacturers, Husqvarna first began producing bicycles in the late 19th century.
Diagram of uniflow scavenging. Scavenging is the process of replacing the exhaust gas in a cylinder of an internal combustion engine with the fresh air–fuel mixture (or fresh air, in the case of direct-injection engines) for the next cycle. If scavenging is incomplete, the remaining exhaust gases can cause improper combustion for the next ...
Husqvarna (pronounced [ˈhʉ̂ːsˌkvɑːɳa] ⓘ) is a Swedish company founded in 1689 to produce muskets. The company has grown since, was partitioned, and is now a brand of multiple companies. The company has grown since, was partitioned, and is now a brand of multiple companies.
The engine operates in HCCI mode at speeds below 60 miles per hour (97 km/h) or when cruising, switching to conventional SI when the throttle is opened and produces fuel economy of 43 miles per imperial gallon (6.6 L/100 km; 36 mpg ‑US) and carbon dioxide emissions of about 150 grams per kilometre, improving on the 37 miles per imperial ...
In crankcase scavenged 2-stroke engines, exhaust and intake are performed mostly simultaneously and with the combustion chamber at its maximum volume. The main advantage of 2-stroke engines of this type is mechanical simplicity and a higher power-to-weight ratio than their 4-stroke counterparts. Despite having twice as many power strokes per ...
Four-stroke cycle used in gasoline/petrol engines: intake (1), compression (2), power (3), and exhaust (4). The right blue side is the intake port and the left brown side is the exhaust port. The cylinder wall is a thin sleeve surrounding the piston head which creates a space for the combustion of fuel and the genesis of mechanical energy.
Internal combustion engines operate through a sequence of strokes that admit and remove gases to and from the cylinder. These operations are repeated cyclically and an engine is said to be 2-stroke, 4-stroke or 6-stroke depending on the number of strokes it takes to complete a cycle. The most common type is 4-stroke, which has following cycles.
