Natural gas fueled vehicle

A natural gas fueled vehicle, comprising:

• a natural gas fueled Internal Combustion Engine (ICE) configured to provide motive power to the vehicle;
• a pressurizable tank disposed on the vehicle, the pressurizable tank being configured to contain a natural gas;
• a natural gas adsorbent disposed in the pressurized tank;
• a fuel supply tube configured to convey the natural gas to the ICE;
• a scroll compressor configured to receive the natural gas and to discharge a first mixture of a compressed natural gas and an oil;
• and
• a two-stage gas and oil separator configured to receive the first mixture of the compressed natural gas and the oil from the scroll compressor, the two-stage gas and oil separator comprising a first stage gas and oil separator in fluid communication with an output of the scroll compressor to separate a first portion of the oil from the first mixture of the compressed natural gas and the oil and discharge a second mixture of the compressed natural gas and the oil to be received by a second stage gas and oil separator to separate a second portion of the oil from the second mixture of the compressed natural gas and the oil to discharge the compressed natural gas to the fuel supply tube substantially free from the oil;
• a compressor bypass valve disposed downstream of the pressurizable tank, the compressor bypass valve being configured to enter a bypass mode to cause the natural gas to bypass the scroll compressor and flow through the fuel supply tube when a tank pressure of the natural gas in the pressurized tank is greater than an uncompressed cut-off pressure;
• and
• a venturi configured to draw the first portion of the oil from the first stage gas and oil separator and the second portion of the oil from the second stage gas and oil separator into a stream of natural gas from the pressurized tank via an oil port in a throat of the venturi.
