Who was responsible for Deepwater Horizon oil spill?
BP
In September 2014, a U.S. District Court judge ruled that BP was primarily responsible for the oil spill because of its gross negligence and reckless conduct. In April 2016, BP agreed to pay $20.8 billion in fines, the largest corporate settlement in United States history.
How much engine blow-by is normal?
When measured in cubic feet per minute (cfm), a 12-liter engine in good mechanical condition can experience at idle 1.5 cfm of blowby at normal operating temperature but 3.5 cfm when cold.
What causes oil in the air intake?
It is caused by excessive carbon deposits or engine sludge developing inside the crankcase. When the oil does not flow efficiently, excessive engine oil pressure will be created and cause extra oil to push through the PCV valve and into the air intake.
Did Andrea Fleytas jump?
Fleytas jumped in. The remaining people on the rig, including Capt. Kuchta, leapt into the Gulf. Something did not just go wrong.
Did anyone from BP go to jail?
BP Exploration and Production Inc. pleaded guilty to 14 criminal counts for its illegal conduct leading to and after the 2010 Deepwater Horizon disaster, and was sentenced to pay $4 billion in criminal fines and penalties, the largest criminal resolution in U.S. history, Attorney General Holder announced today.
Is a little blow-by bad?
If it immediately blows off, there definitely is too much crankcase pressure. Blow-by also results in contaminated (by unburned fuel), diluted oil in the engine’s crankcase. In some instances where blow-by is excessive, the mixture can cause a diesel to run away if it reaches the combustion chamber.
What is blow-by at idle?
Blow-by occurs when the explosion that occurs in your engine’s combustion chamber causes fuel, air and moisture to be forced past the rings into the crankcase. Your engine’s rings must maintain an excellent fit in order to contain the pressure. Blow-by inhibits performance because it results in a loss of compression.
How to avoid common causes of blow by and oil consumption?
Here are some common causes of blow-by and excessive oil consumption and how you can avoid them on your next engine build. The combustion process is never perfect. Even the best street engine never seals all that combustion pressure. A certain amount of cylinder pressure will always find its way into the oil pan.
What causes the oil to blow by in a diesel engine?
Causes of Diesel Engine Oil Blow By. by Tony Oldhand. In a diesel engine, blow by is defined as the compressed fuel/air mixture in the combustion chamber leaking past the piston and entering the crankcase. Blow by is not good since it robs engine power and builds up gas pressure in the crankcase.
What happens when oil is mixed with blow by?
Mixed by a spinning crankshaft, combustion by-products churn with partially vaporized oil in a witch’s brew that, if not properly vented and managed, can be problematic. Windage is also involved in any discussion regarding crankcase pressure since oil is the viscous fluid that we must deal with.
Why does the oil blow out of the crankcase?
Bear in mind that aluminum is a soft metal, and grit accumulation in the combustion chamber carves grooves into the piston. These grooves are an ideal place for the compressed fuel/air mixture to escape into the crankcase.
