Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
increases imagination and understanding
improves your listening skills
improves your own spoken accent
learn while on the move
reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
The Family II is a straight-4 piston engine that was originally developed by Opel in the 1970s, debuting in 1979. Available in a wide range of cubic capacities ranging from 1598 to 2405cc, it simultaneously replaced the Opel OHV, Opel CIH and Vauxhall Slant-4 engines, and was GM Europe's core powerplant design for much of the 1980s.
The engine features a cast iron block, an aluminium head, and a timing belt driven valvetrain. The timing belt also drives the water pump. It was first used in the Opel Kadett D, Ascona B, Corsa, and their corresponding Vauxhall sister models, the Astra, Cavalier, and Nova. Many General Motors subsidiaries, including Daewoo, GM do Brasil, GM Powertrain, and Holden have used this design.
By 1986, the Family II unit had completely supplanted the CIH engine as Opel's core 4-cylinder powerplant. although the 6-cylinder versions of the CIH continued in the larger Omega and Senator models until 1995.
In 2004, a 2.0 L MultiPower engine was made available for the taxi market which could use gasoline, alcohol, and natural gas.
The Family II also spawned two diesel variants, the 1.6 L and 1.7 L. These engines are sometimes referred to as "Big-block" engines by enthusiasts; in contrast to the smaller Family 1 engines which are sometimes referred to as the "Small-block" engines.
The development track of these engines split in 1987, with the introduction of the 20XE; which featured a 16-valve DOHC head. Although SOHC versions are still in production in Brazil, most DOHC engines were replaced by the all-aluminium GM Ecotec engine family.
Holden made various Family II engines for Opel, GM Daewoo, GM India, GM Uzbekistan and Isuzu Thailand at its Port Melbourne plant. Variations include displacements from 1.8 L to 2.4 L.
