Modern hedge trimmers come in all shapes and sizes. Okay, they all look pretty similar in shape, but you know what I mean!<\/p>\n\n\n\n

<\/span>The Petrol Hedge Trimmer<\/strong><\/span><\/h2>\n\n\n\n
While the other types of hedge trimmer have a motor, the petrol model has an engine. Now, this is not exactly like the engine in your car but on a smaller scale. This is a 2-stroke <\/em>engine.<\/p>\n\n\n\n
This means that you can’t just fill it up with standard unleaded from Tesco and away you go! If you do so, you’ll soon regret it. We’ll discover why in a moment,<\/p>\n\n\n\n
<\/span>What does ‘2-stroke engine’ mean?<\/strong><\/span><\/h3>\n\n\n\n
Without getting too technical, it means that the engine completes one power cycle<\/em> in two movements (or strokes) of the piston, up and down. To put it another way, your car (unless it’s electric!) has a 4-stroke engine, meaning that the power cycle has four stages; intake, compression, power, and exhaust. That means it goes through two complete revolutions of the crankshaft to complete one power cycle.<\/p>\n\n\n\n
Fuel is sprayed into a chamber, squeezed, ignited to give a burst of energy that pushes the piston around, and the resulting exhaust is pumped out the other end. All good so far? Great!<\/p>\n\n\n\n
In 2-stroke engines, this procedure is completed in only two stages, as intake and exhaust happen simultaneously. So, it only takes the up and down movement (two strokes: compression and power) of the piston to turn the crankshaft one full revolution. It’s as simple as that!<\/p>\n\n\n
