June 22, 2008, Sunday

Trying for the last five days to go for a morning walk. But today also i slept till 9am. Tomorrow i may go for a walk at 6am. Lets wait and see what happens. Played with Yuthi for sometime. Applied for the openings which is shown in Bangalore Times. Chechi asked to buy crab and fish. She likes crab but i don like it. Put my trainers and went to Frostys to buy wish. As its sunday lots of people were there. I have to wait for sometime. Bought crab and redfish. Chechi told me to buy coconut and milk also. So went to Mallu chettans kada and bought them also. Was planning to go to Hari's place as he is not very well. He says because of eating chips. How can one get fever by eating chips? Hari is always special. May be cz of dat. Hari ringed and said he is gng to his relatives home at Jeevanbhima Nagar. So i settled home once again. Evening called my bro kuttu and asks him to send some text books thru chikku chettan. Chikku chettan is coming from trivandrum as he went to ernakulam to see chinthu chettans baby girl. Evening watched formula one and motogp. Kimi got problems with his exhaust pipe and have to settle for a second. Rossi scores a second. Stoner was way too fast. Slept Yuthimon in my lap at night. Don know y he always sleep once i took him in my lap!!!

Diesel Engine vs Petrol Engine

The petrol and diesel fuels are energy dense liquids. Both fuels produce large quantities of heat when burns inside the cylinders. The energy thus produced is the source of power for the engine. The fuel burns inside the cylinder causing the trapped air inside the cylinder to expand forcefully. The expansion of air results in driving down the piston. This force is transferred to the piston rod. The piston rod drives the crankshaft. The crankshaft drives the gearbox, driveshaft and finally wheels.

Diesel engines operate at higher pressures. Diesel engines rotate more forcefully and have higher torque. Petrol engines operate at lower pressures. So they are more lightly constructed. Petrol engines rotate more quickly. This results in higher horsepower.

Petrol engines pre-mix the air and fuel. The mixture is conveyed into the engine cylinder. The mixture is compressed. A spark plug is used to ignite the air-fuel mixture. Diesel engines compress air inside the engine cylinder to higher temperatures. The fuel is sprayed into the compressed air using a fuel injector resulting in combustion.

Diesel engines have longer and narrower engine cylinders. Thus maximum pressure can be created for combustion. One stroke of the piston takes more time, but produces more torque. Petrol engines have shorter and flatter engine cylinders. One stroke of piston takes considerably less time. This causes faster spinning and more horsepower. Turbochargers and direct fuel injection systems are applied to new age diesel engines to generate more horsepower by speeding up the spinning process.

Diesel engines have a wider power band. So fewer gear changes are required resulting in more comfortable drive.

Bangalore City. A very beautiful place. Came here 3 months back in search of job. Application ayachu maduthu. Not a single interview call till now. Morning to evening books vaayikkuva, TV kanuva; vere nothing to do. Enna bore adiya. Chettan and Chechi saturday aavan wait cheyyum, as both are working. Two days suhamayi veettil irikkamello ennu!! Veettil irunnu maduthittu veyya. Engottelum karangaan povaamennu vachaal frends orennam polum available alla. Ellarum full busy. Ennenkilum job aavumbol oru kaaryam orappichu, I will work on saturday and sunday also.
