cast aluminium alloy; four unequal-length valves per cylinder, 24 valves total, low-friction roller finger cam followers with automatic hydraulic valve clearance compensation, simplex roller chain-driven double overhead camshaft (DOHC – one camshaft for all exhaust valves, and one for all intake valves), continuous timing adjustment variable ...
The Volkswagen EA211 engine (EA = development order), also called modular gasoline engine kit, is a family of inline-three and inline-four petrol engines with variable valve timing developed by Volkswagen Group in 2011. [1] They all include a four-stroke engine and dual overhead camshaft drive into exhaust manifolds. [1]
The Polo Mk5 was relaunched in South Africa in February 2018 as the Polo Vivo. It replaced the Polo Mk4-based Polo Vivo and sold alongside the Polo Mk6 as a budget-friendly option. [31] [32] The Polo Vivo is offered in four trim levels including Trendline, Comfortline, Highline, and GT. Two 4-cylinder petrol engines are offered, a 1.4-litre and ...
The Mark III Polo or Typ 6N, (sometimes referred to as the "Mark 4" by enthusiasts as it is the Polo's fourth guise) appeared in 1994, [1] [10] and was a completely new model (on a new chassis), available as three- and five-door hatchback versions, the latter making VW the last major European manufacturer to finally offer rear side doors in ...
A pair of poppet valves bent by collision with a piston after timing belt failure. The engine was running at 4500 RPM. In interference engine designs, replacing a timing belt in regular intervals (manufacturers recommend intervals ranging from 60,000 to 104,000 miles) or repairing chain issues as soon as they are discovered is essential, as incorrect timing may result in the pistons and valves ...

The timing, duration and lift of these valve events has a significant impact on engine performance. Without variable valve timing or variable valve lift, the valve timing is the same for all engine speeds and conditions, therefore compromises are necessary to achieve the desired result in intake and exhaust efficiency . This has been described ...
