Investigators ruled out self-ignition
as the cause because the rest of the truck was intact.
With respect to damage to the motor vehicle, the coverage to the insured vehicle, its accessories and spare parts, include: a) accidental collision or overturning, or collision or overturning consequent upon mechanical breakdown or consequent upon wear and tear; b) fire, external explosion, self-ignition
or lightning or burglary, housebreaking, or theft; c) malicious act; and d) whilst in transit (including the processes of loading and unloading) incidental to such transit by road, rail, inland waterway, lift or elevator.
In a press conference for announcing the ministry's plan for countering the black clouds in 2018, Fouad explained that despite the decrease in cultivated land of rice this year, the mission for countering air pollution is not easy as burning the rice straw is not the only reason for the black clouds phenomena, but there are additional reasons, such as the self-ignition
of the random dumps and the emissions of the industrial institutions and vehicles exhausts.

of n-Heptane-Air Mixtures under Engine Relevant Conditions," Combustion and Flame 93(4):421-433, 1993.
"This innovation is the first of its kind worldwide and has very high efficiency and self-ignition
with catalyst e-stones [composite material made of crushed stone] driven by renewable energy."
In the history of field development with the help of air injection there are cases where self-ignition
of low-viscosity, light oil did not occur, such as Arlankovsky field 24[degrees]C, 30[degrees] API .
Spontaneous combustion is the self-ignition
of a material.
The aforementioned is because increased compression ratio (CR) increases the tendency for the occurrence of a phenomenon denominated self-ignition
, which takes place when at the start of the combustion in the air-fuel mixture happens prior to the spark ignition, which causes quite high pressure peaks and a shock wave within the chamber.
It takes into account the amount of time passing from injecting the fuel to self-ignition
In order to investigate the flammable properties of seven analyzed polyester materials, the following parameters were determined: combustion heat, the ignition temperature of volatile products of thermal decomposition, self-ignition
temperature and oxygen indexes of the studied polyesters.
Calling the 421 tonnes of munitions a "ticking time bomb," the report found the explosion was due to self-ignition
of the containers, and ruled out the possibility that an outside source of heat (such as a brushfire) caused the blast.
