Diesel engine and Petrol engine ( Comparison ) Essay

Diesel engine and Petrol engine ( Comparison ) - Essay Example Despite their derivation from crude oil, the use of petrol or diesel engine varies according to the particular needs of the consumer who will drive the automobile such as fuel prices, fuel efficiency, fuel economy, running cost, taxes, etcetera (â€Å"Choosing between petrol and diesel†, 2013; â€Å"Buying A Car - Do I Choose Petrol Or Diesel?†, 2012; Foxall, 2012; Ottley, 2010; Work Truck Magazine, 2011). In terms of their chemical properties, diesel is denser than petrol and generates more energy upon combustion (Bloom, 2010). By design, a petrol engine consists of connecting rods, brasses, strap, jibs, cotter and set screws (Narayana, Kannaiah and Reddy 2007, 359). The major difference between a diesel engine and a petrol engine, apart from the different fuels, comes from the way in which fuel is combusted inside the piston cylinder. Fuel in the petrol engine is mixed with air, compressed by the pistons and then ignited by the spark provided from the spark plugs. On the other hand, a diesel engine differs in terms of the stage when air is compressed. As opposed to a petrol engine, air in a diesel engine is compressed first after which fuel is injected and ignited as the air heats up after being compressed (Brain, 2014). This essay will present an evaluative comparison of diesel and petrol engines in terms of their design and functioning. The engine’s compression ratio concerns to the amount to which the gasses can be squeezed into the engine’s cylinder. The higher the engine’s compression ratio the more preferable it is because compression generates high amounts of heat (â€Å"Difference between Diesel and Gasoline Engines†, 2012). Compression involves blending and evaporating the fuel and air molecules, which mix with each other appropriately by being thrusted together into a smaller and tighter area. High compression ratio in an engine enables the generation of greater power by burning fuel and

Developing a Christian Mind - Essay Example However, it also means, according to Strongs Concordance (Strong 7965), completeness, wholeness, health, peace, welfare, safety soundness, tranquility, prosperity, perfectness, fullness, rest, harmony, the absence of agitation or discord. Shalom is a blessing (The Refiners Fire). There are three levels of Christian relationship. We are called to be in relationship with God, with God’s creation, and with others (Lowe and Claiborne). Our relationship with God is the most basic and critical. That relationship was a gift to us, through Jesus, the life-giver. When Jesus ascended to heaven, he left us the Holy Spirit, so that his ministry is still alive, still dynamic, still with us. By tuning into the leading of the Holy Spirit, and responding to that leading, we can stay within God’s plan for our lives. In that way, God is not something far away and external to us, but is internal and immediate. This is the deepest source of peace, of wholeness, completeness, health, welfare, safety, soundness, tranquility, prosperity, perfectness, fullness, rest, harmony, the absence of agitation or discord. Shalom is God’s blessing. What that looks like, in operation, is that a Christian reads God’s Word, prays deeply, listens to the silence in which God speaks. The peace, Shalom, shows in action, in word, in expression, in patience, in gentleness, in modesty. It shows in a Christian’s embodiment of all the virtues that lead to the other levels. The next level is a Christian’s relationship to God’s creation. Loving God and feeling his love for us, leads us to a great respect for his creation. In the flight of each flamingo, in the wing pattern of each butterfly, in the purity of snow on a mountaintop, in the startle of lightening, in the reflection of creation in the still surface of a lake, in the mist from a thundering waterfall, in the paw of a squirrel, in the whir of the hummingbird, in the strength of an ant and the
